Key Ingredients and Smart Substitutions for Caprese Spaghetti Squash Boats
Crafting these delectable Chicken Caprese Spaghetti Squash Boats requires a few simple yet essential ingredients. Here’s a breakdown of what you’ll need and how you can creatively adapt the recipe to your preferences or what you have on hand:
- Spaghetti squash – This versatile winter squash is the star of our low-carb dish, providing a pasta-like texture without the carbohydrates. If you’re looking for an alternative, zucchini noodles (zoodles) are an excellent choice for maintaining the low-carb profile, or you could even use roasted eggplant slices for a different twist.
- Olive oil – A good quality olive oil is crucial for roasting the squash and enhancing the overall Mediterranean flavors. If you don’t have olive oil, other neutral oils like sunflower seed oil, grapeseed oil, or avocado oil will work effectively for cooking, though they might slightly alter the aroma.
- Chicken breast – Lean and protein-packed, diced chicken breast absorbs flavors wonderfully. For an even juicier and richer taste, boneless, skinless chicken thighs can be used and will cook beautifully in the squash boats. Ensure all chicken is diced into small, even pieces for quick and thorough cooking.
- Cherry tomatoes – These small, sweet tomatoes burst with flavor when baked, adding a delightful acidity and freshness. Grape tomatoes are an ideal substitute, and even standard salad tomatoes or plum tomatoes, chopped into bite-sized pieces, will work, though plum tomatoes tend to be less juicy.
- Bocconcini cheese – These small, fresh mozzarella balls melt beautifully and offer a creamy, milky contrast to the other ingredients. Fresh mozzarella, either in a larger ball sliced or pearl form, is a perfect substitute.
- Fresh basil – The aromatic essence of fresh basil is irreplaceable in Caprese dishes. It adds a vibrant, peppery, and sweet note. While fresh is definitely best, if you’re in a pinch, fresh spinach leaves can provide a green element, though the flavor profile will be different. Avoid dried basil for this recipe, as its flavor is not comparable to fresh.
- Salt & pepper – Essential for seasoning, these staples bring out the best in all ingredients. Adjust to your personal taste preference throughout the cooking process.
For the Homemade Balsamic Glaze:
- Balsamic vinegar – The foundation of any balsamic glaze, its rich, tangy notes reduce into a thick, sweet syrup. There’s no true substitute for balsamic vinegar to achieve this specific glaze, so ensure you have this on hand.
- Brown sugar – This adds sweetness and helps the glaze thicken into a glossy consistency. If you’re out of brown sugar, other sweeteners like honey or maple syrup can be used, keeping in mind they might impart a slightly different flavor. You can also adjust the amount to your desired level of sweetness.

Simple Steps to Create Perfect Chicken Caprese Spaghetti Squash Boats
Making these flavorful spaghetti squash boats is a straightforward process. Follow these easy steps to bring this healthy and delicious meal to your table:
- Prepare and Partially Bake the Squash: Begin by preheating your oven. Microwaving the spaghetti squash halves for a few minutes before baking helps to soften them, making them much easier and safer to cut. Once cut and deseeded, drizzle them with olive oil, season with salt and pepper, and then bake them to start the cooking process. This initial bake ensures the squash is tender enough to scrape and continues cooking while infused with the chicken’s flavors.
- Scrape Out the Flesh: After the initial bake, carefully remove the squash from the oven. Using a fork, gently scrape out some of the spaghetti-like strands from the squash halves. Don’t worry about getting every strand; the goal is to create space and allow for better integration of the chicken and other ingredients. The remaining squash will continue to cook and tenderize with the added fillings.
- Add Chicken and Continue Cooking: Fill each partially hollowed spaghetti squash boat with the diced raw chicken. Return the boats to the oven to allow the chicken to cook thoroughly and absorb the squash’s natural sweetness and the olive oil’s richness.
- Prepare the Balsamic Glaze: While the chicken is cooking, you can prepare your balsamic glaze. If you’re making it from scratch, combine balsamic vinegar and brown sugar in a saucepan and simmer until it reduces to a thick, syrupy consistency. This sweet and tangy glaze will be the crowning glory of your dish. Alternatively, use a high-quality store-bought balsamic glaze to save time.
- Final Bake with Tomatoes and Cheese: Once the chicken is nearly cooked through, add the fresh cherry tomatoes and bocconcini cheese to each squash boat. Bake again until the tomatoes soften and begin to burst, and the cheese is beautifully melted and bubbly. This final bake integrates all the Caprese flavors into a warm, inviting dish.
- Garnish and Serve: Remove the perfectly baked spaghetti squash boats from the oven. Generously sprinkle fresh basil leaves over each boat, adding a vibrant aroma and fresh taste. Finish with a generous drizzle of your homemade or store-bought balsamic glaze. Serve immediately and savor every forkful of this exquisite low-carb dinner!

Embrace Health: The Nutritional Benefits of Spaghetti Squash
Absolutely, spaghetti squash is a remarkably healthy and nutritious vegetable, celebrated not just for its unique pasta-like strands but also for its impressive nutrient profile. It serves as an excellent low-carb alternative to traditional pasta, allowing you to enjoy comforting meals while maintaining a healthy diet.
Here are some of the outstanding nutritional benefits that make spaghetti squash a powerhouse vegetable:
- Low in Carbs and Calories: For those managing carbohydrate intake or looking to reduce calorie consumption, spaghetti squash is a game-changer. It offers significantly fewer calories and carbohydrates compared to traditional pasta, making it a perfect choice for keto, paleo, or weight-management diets.
- Rich in Antioxidants: This vibrant squash is packed with beneficial antioxidants, including a great source of Vitamin C and beta-carotene. Antioxidants help protect your cells from damage caused by free radicals, supporting overall health and potentially reducing the risk of chronic diseases. Beta-carotene is also converted to Vitamin A in the body, which is vital for vision, immune function, and skin health.
- Excellent Source of Fibre: Spaghetti squash is abundant in dietary fiber, which is crucial for digestive health. Fiber aids in maintaining regular bowel movements, preventing constipation, and supporting a healthy gut microbiome. It also contributes to satiety, helping you feel fuller for longer and potentially assisting with weight control.
- Loaded with Vitamins and Minerals: Beyond Vitamin C and beta-carotene, spaghetti squash provides a good array of other essential vitamins and minerals, including Vitamin B6, niacin, manganese, and potassium. These nutrients play vital roles in energy metabolism, nerve function, blood pressure regulation, and bone health, contributing to your overall well-being.
- Versatile and Flavorful: Its mild, slightly sweet flavor makes it incredibly versatile, easily absorbing the tastes of whatever ingredients it’s paired with. This allows for a wide range of culinary applications, from savory dishes like these Caprese boats to sweeter preparations, making healthy eating both exciting and delicious.
Incorporating spaghetti squash into your diet is a smart and tasty way to boost your nutrient intake while enjoying satisfying, wholesome meals.

Frequently Asked Questions About Chicken Caprese Spaghetti Squash Boats
Here are some common questions about cooking with spaghetti squash and preparing this delicious Caprese recipe:
Spaghetti squash has gained immense popularity as a healthy, low-carb alternative to regular pasta primarily due to its unique texture. When cooked, its flesh separates into thin, noodle-like strands, strikingly similar in appearance to spaghetti. However, while the texture is comparable, its taste is distinct. Spaghetti squash offers a slightly neutral and subtly sweet flavor, which is milder than conventional pasta. The real magic happens when you combine it with flavorful ingredients like the chicken, vibrant cherry tomatoes, creamy bocconcini cheese, fresh basil, and a sweet-tangy balsamic glaze in this recipe. These bold Caprese flavors beautifully complement the squash, making it so delicious that you’ll hardly notice the subtle difference from traditional pasta!
For this particular recipe, the spaghetti squash requires a two-stage cooking process. You’ll first need to bake the squash halves on their own for approximately 25 minutes to get them partially tender and easy to scrape. After adding the chicken and other toppings, they will return to the oven for additional cooking. The total baking time, including the chicken, tomatoes, and cheese, comes to about 45 minutes. While it might seem a bit lengthy, the layered baking ensures all components are perfectly cooked and infused with flavor, making every minute absolutely worth it for a truly satisfying meal!
Caprese chicken is a delicious Italian-inspired chicken dish that draws its name and flavor profile from the classic Caprese salad. Traditionally, it features tender chicken breasts topped with fresh slices of mozzarella cheese, sweet ripe tomatoes, and fragrant fresh basil, often drizzled with olive oil and a balsamic glaze. This recipe offers a fantastic low-carb spin on that beloved classic. Instead of serving the chicken with regular pasta or rice, we nestle all those wonderful Caprese ingredients into roasted spaghetti squash “boats,” turning a classic into a wholesome, flavorful, and incredibly satisfying low-carb meal. It retains all the essence of Caprese while cleverly utilizing spaghetti squash as a healthy vessel.
Absolutely! To streamline your cooking process, you can prepare a few elements ahead of time. The spaghetti squash can be microwaved and partially baked, then stored in the fridge for up to 2-3 days. You can also dice the chicken breast and slice the bocconcini cheese in advance. The balsamic glaze can be made and stored in an airtight container at room temperature for up to a week. Having these components ready will significantly cut down on active cooking time when you’re ready to assemble and bake your delicious Caprese spaghetti squash boats.

Storing and Reheating Your Spaghetti Squash Boats
These Chicken Caprese Spaghetti Squash Boats are wonderful fresh out of the oven, but they also make fantastic leftovers! To store any remaining portions, allow them to cool completely before transferring them to an airtight container. They will keep well in the refrigerator for up to 3 days. When you’re ready to enjoy them again, simply reheat the spaghetti squash boats in the oven at 350° Fahrenheit (175°C) until they are fully warmed through, usually around 15-20 minutes. Reheating in the oven helps maintain the texture of the squash and keeps the cheese from becoming rubbery, unlike microwave reheating which can make the squash watery.
Freezing This Recipe: Tips and Tricks
Unfortunately, the fully assembled Chicken Caprese Spaghetti Squash Boats do not freeze particularly well due to the moisture content of the squash and the delicate texture of the cheese and tomatoes, which can become mushy upon thawing and reheating. However, you can certainly freeze the spaghetti squash on its own to save time for future meals. To do this, cook the squash until tender, then scoop out the “noodles” and allow them to cool completely. Transfer the spaghetti squash strands to an airtight freezer-safe container or a heavy-duty freezer bag, removing as much air as possible. The frozen squash will last for up to 6 months. When you’re ready to use it, simply thaw it overnight in the fridge and then follow the regular cooking instructions to assemble your Caprese boats with fresh chicken and toppings.

Ingredients
- 2 medium spaghetti squash, cut in half lengthwise
- 1 tbsp olive oil, for drizzling
- 2 boneless, skinless chicken breasts, diced into 1-inch pieces
- 1 package Cherry or grape tomatoes
- 1 package Bocconcini cheese, drained and halved
- 1 cup fresh basil leaves, roughly chopped or left whole
- Salt & freshly ground black pepper to taste
For the Balsamic Glaze
- 1/3 cup balsamic vinegar
- 3 tbsp brown sugar (or honey/maple syrup for variation)
Instructions
-
Preheat your oven to 425° F (220°C). To make cutting easier, microwave each spaghetti squash half for 2-4 minutes (adjusting time based on size) until slightly softened. Carefully cut the squash in half lengthwise and scoop out the seeds. Drizzle the cut sides with olive oil, season generously with salt and pepper, then place cut-side down on a baking sheet. Bake for 25 minutes.
-
Remove the spaghetti squash from the oven. Using a fork, gently scrape out some of the cooked flesh to create a cavity within each squash half. Don’t worry if it’s not fully “noodled” yet; the rest will develop during the final cook. Top each squash boat evenly with the diced raw chicken breast. Return to the oven and bake for another 10 minutes to partially cook the chicken.
-
While the chicken is cooking, prepare your balsamic glaze (if not using a store-bought version). In a small saucepan, combine balsamic vinegar and brown sugar. Bring the mixture to a boil over medium heat, then reduce the heat to medium-low and simmer for about 10 minutes, or until the glaze thickens to a syrupy consistency, coating the back of a spoon. Be careful not to over-reduce, as it will thicken further as it cools.
-
Take the spaghetti squash boats out of the oven once more. Distribute the cherry tomatoes and bocconcini cheese evenly over the chicken in each boat. Place them back into the oven and bake for an additional 10 minutes, or until the cherry tomatoes begin to softly burst and the bocconcini cheese is beautifully melted and slightly golden.
-
Carefully remove the finished Caprese spaghetti squash boats from the oven. Garnish generously with fresh basil leaves for an aromatic finish, then drizzle with your prepared balsamic glaze. Serve immediately and enjoy this vibrant and healthy low-carb meal!

Helpful Tips & Notes
Time-Saving Hack: To significantly cut down on prep time, consider using a good quality store-bought balsamic glaze instead of making your own. This doesn’t sacrifice flavor and gets dinner on the table faster.
Storage & Reheating: Store any cooled leftovers in an airtight container in the fridge for up to 3 days. For best results, reheat in the oven at 350° F (175°C) until fully warmed, helping to maintain the squash’s texture and prevent the cheese from becoming overly soft.
