Crafting Your Instant Pot Pizza Quinoa Casserole: A Step-by-Step Guide
Creating this delicious and healthy Instant Pot Pizza Quinoa Casserole is incredibly simple. Follow these straightforward steps to enjoy a fantastic meal in no time:
-
Begin by adding 2 cups of chicken broth to your Instant Pot. Next, add 2 cups of sliced mushrooms, followed by 1 cup of dried quinoa. It’s important to layer the quinoa on top as specified for optimal cooking. Secure the lid on your Instant Pot, ensure the vent is sealed, and set it to pressure cook on high for 2 minutes. The Instant Pot will typically take about 10 minutes to come to pressure before the 2-minute cooking cycle begins. Once cooking is complete, press “cancel” and perform a quick release of the steam. Wait until the pressure gauge drops completely, indicating it’s safe to open the lid.
-
Carefully remove the lid. Now, it’s time to incorporate those vibrant pizza flavors! Add 2 cups of your favorite pizza sauce, along with 1 diced green bell pepper and 1 sliced red onion. Stir everything gently to combine, ensuring the cooked quinoa and vegetables are well coated. Replace the lid (without sealing or setting pressure) and let the mixture sit for 5 minutes. This brief resting period allows the heat to gently soften the fresh vegetables, enhancing their flavor and texture. After 5 minutes, remove the lid again and stir in the 1 package of turkey pepperoni. Give it another good stir to evenly distribute the pepperoni throughout the casserole.
-
Once the casserole is ready, divide the flavorful mixture into 6 individual servings or into as many bowls as you need for immediate consumption. Generously top each serving with 1 cup of shredded mozzarella cheese. For that perfectly melted, gooey cheese topping, microwave each individual serving for 2 minutes. The cheese will become beautifully bubbly and golden. Serve immediately and savor every bite of this quick and satisfying Instant Pot Pizza Quinoa Casserole! Remember, for optimal storage, it’s best to store any unserved portions without the melted cheese (see the “Storing and Reheating” section below for more details).
Essential Ingredients and Flavorful Substitutions
This Instant Pot Pizza Quinoa Casserole is wonderfully versatile, allowing for various ingredient swaps to suit your pantry or dietary preferences. Here’s a breakdown of the key components and their potential alternatives:
- Chicken broth: The broth forms the flavorful base for cooking the quinoa. While chicken broth adds a rich poultry note, you can easily substitute it with vegetable broth for a vegetarian version, or even beef broth for a deeper, more robust flavor profile. Just ensure you use a good quality broth for the best taste.
- Mushrooms: Earthy and savory, mushrooms add a fantastic texture and umami depth. If mushrooms aren’t your favorite, or if you simply don’t have them on hand, feel free to replace them with another vegetable you enjoy, such as diced zucchini, bell peppers (beyond the green one already included), or even spinach (added during the second step to prevent overcooking). Alternatively, you can omit them entirely if you prefer a simpler veggie base.
- Dried quinoa: Quinoa is the star grain here, providing a gluten-free, protein-rich foundation. A fantastic and similar substitute for quinoa is couscous, which also cooks quickly and offers a delightful texture. If using couscous, keep in mind that the cooking time might vary slightly, and more importantly, the nutritional facts of your final dish will change, as couscous is not gluten-free and has a different macronutrient profile.
- Pizza sauce: This is crucial for that authentic pizza taste. If you’re out of store-bought pizza sauce, you can easily create a homemade version. Simply use a good quality canned crushed tomatoes or tomato paste mixed with water, and season it generously with essential Italian spices such as dried oregano, garlic powder, onion powder, and a touch of Italian seasoning. A pinch of sugar can balance the acidity if needed.
- Turkey pepperoni: We’ve opted for turkey pepperoni for a leaner protein choice, which provides that classic spicy, savory kick. However, this recipe is incredibly forgiving, so feel free to use any other variant of pepperoni you prefer, whether it’s traditional pork pepperoni, beef pepperoni, or even a vegetarian pepperoni substitute for a meat-free option. Sliced ham, cooked sausage, or diced cooked chicken breast could also work wonderfully here for a different protein twist.
- Green bell pepper: The green bell pepper adds a fresh, slightly bitter, and crisp element. While green is classic, any other bell pepper color—red, yellow, or orange—will work perfectly and add a touch of sweetness. If bell peppers aren’t your preference, consider swapping them for diced celery, thinly sliced carrots, or even small broccoli florets, added during the softening stage. You can also leave them out completely if you prefer fewer vegetables.
- Red onion: Red onion offers a pungent, slightly sweet, and vibrant flavor that brightens the casserole. For substitution, white onion, yellow onion, or even shallots can be used. Each will impart a slightly different flavor intensity, with shallots being milder and yellow onions being a bit stronger when cooked.
- Mozzarella cheese: Mozzarella is undeniably the best option for this pizza casserole due to its incredible melt factor and mild, creamy taste that complements pizza flavors perfectly. However, if you’re looking to experiment or use what you have, feel free to replace it with any other grated cheese of your choice, such as a sharp cheddar, provolone, or a mixed Italian blend for added complexity.
- Basil (to garnish): Fresh basil leaves add a wonderful aromatic finish and a pop of color.
- Red chili flakes (to garnish): A sprinkle of red chili flakes is optional but highly recommended for those who enjoy a little extra heat and a subtle spicy kick.
Storing and Reheating Your Casserole for Maximum Freshness
Proper storage is key to extending the delicious life of your Instant Pot Pizza Quinoa Casserole, especially when it comes to the cheese. To ensure your leftovers remain fresh and appetizing for as long as possible, we recommend a specific storage method:
When you’re ready to store your pizza quinoa casserole, it’s crucial to portion your meals out by serving and refrigerate them *without* the melted cheese on top. Transfer each serving into its own airtight container. This method allows the casserole base to maintain its optimal texture and flavor. Stored in this manner, your casserole will keep beautifully in the refrigerator for up to 4 days.
The reasoning behind storing the casserole without the melted cheese is simple yet effective. Melted cheese, when refrigerated, can become rubbery and less appealing. Furthermore, leftovers that have the melted grated cheese on top will only last for 1-2 days before the texture and freshness begin to decline. By keeping the cheese separate and adding it fresh upon reheating, you’re not only extending the shelf life of your leftovers but also breathing some new life and deliciousness back into them with every meal. You’ll enjoy that perfectly gooey, freshly melted cheese every single time.
When you’re ready to enjoy a serving from the fridge, simply take the airtight container out. Sprinkle your fresh, grated mozzarella or preferred cheese generously over the cold casserole mixture. Then, microwave it for 1-2 minutes, or until the casserole is thoroughly warmed through and the cheese is melted and bubbly. For best results, stir the casserole halfway through microwaving, then add the cheese and continue heating until melted. This ensures even heating and prevents dry spots. This simple step ensures your reheated meal tastes just as delightful as when it was first made!
Freezing This Recipe for Future Meals
One of the many benefits of this Instant Pot Pizza Quinoa Casserole is its freezer-friendliness, making it an excellent option for meal prep or emergency weeknight dinners. You have a couple of options for freezing:
You can freeze the entire casserole in one large freezer-friendly container, such as a glass baking dish with an airtight lid, after it has completely cooled. Alternatively, for ultimate convenience and easy access, divide the cooled casserole into individual servings before freezing. This allows you to grab a single portion for a last-minute freezer meal without thawing the entire batch. Your prepared casserole will last wonderfully in the freezer for 1-2 months. To reheat from frozen, transfer a single serving to the refrigerator overnight to thaw, then follow the reheating instructions above (adding fresh cheese before microwaving). If reheating directly from frozen, you may need to microwave it for 3-5 minutes, stirring halfway through, then adding cheese and continuing to microwave until hot and bubbly.
Why Quinoa is a Superfood Choice for Your Casserole
Choosing quinoa as the base for this pizza casserole isn’t just about making it gluten-free; it’s about boosting the nutritional value significantly. Quinoa is a complete protein, meaning it contains all nine essential amino acids, which is rare for a plant-based food. This makes it an excellent choice for vegetarians, vegans, or anyone looking to increase their protein intake. Beyond protein, quinoa is rich in fiber, which aids digestion and helps you feel fuller for longer, preventing overeating. It’s also packed with vital minerals like magnesium, potassium, iron, and zinc, as well as antioxidants. Its mild, slightly nutty flavor and fluffy texture absorb the rich pizza sauce perfectly, making it a delicious and incredibly healthy alternative to traditional pasta or rice-based casseroles. Incorporating quinoa into your diet is a simple way to elevate your meals with wholesome goodness.
Tips for the Perfect Instant Pot Pizza Quinoa Casserole
Achieving a consistently perfect casserole every time is easier with a few simple tips:
- Don’t Skimp on Broth: The amount of liquid is critical for perfectly cooked quinoa in the Instant Pot. Stick to the specified amount for fluffy, not mushy, results.
- Layering Matters: Adding quinoa last helps prevent it from settling at the bottom and potentially burning or getting unevenly cooked.
- Vent Release Safety: Always perform a quick release of pressure carefully, standing back from the vent to avoid steam burns.
- Customizing Vegetables: Feel free to add other quick-cooking vegetables like diced zucchini or corn during the second step with the pizza sauce. For tougher vegetables like carrots or potatoes, consider adding them with the quinoa and broth to ensure they soften properly.
- Cheese Selection: While mozzarella is traditional, a blend of cheeses like mozzarella and a touch of Parmesan or provolone can add more depth of flavor.
- Spice it Up: Don’t hesitate to add extra Italian seasoning, dried oregano, or a pinch of red pepper flakes to the pizza sauce for an extra flavor boost.

Ingredients
- 2 cups chicken broth
- 2 cups sliced mushrooms
- 1 cup dried quinoa
- 2 cups Pizza Sauce
- 1 package turkey pepperoni (or regular pepperoni, diced ham, or cooked sausage)
- 1 green bell pepper, diced (or any color bell pepper of choice)
- 1 small red onion, sliced (or white/yellow onion, or shallots)
- 1 cup shredded mozzarella cheese (for topping, or use a preferred cheese blend)
- Fresh Basil (to garnish, optional)
- Red Chili Flakes (to garnish, optional)
Instructions
-
Carefully add 2 cups of chicken broth to the inner pot of your Instant Pot. Next, add 2 cups of sliced mushrooms, distributing them evenly. Finally, gently pour 1 cup of dried quinoa on top of the other ingredients, being careful not to stir. Secure the lid on your Instant Pot, ensuring the sealing ring is properly in place and the steam release valve is set to the “Sealing” position. Set the Instant Pot to “Manual” or “Pressure Cook” mode on High pressure for 2 minutes. The Instant Pot will take approximately 10 minutes to build pressure before the 2-minute cooking cycle begins. Once the cooking time is complete, press the “Cancel” button. Immediately perform a quick release of the pressure by carefully moving the steam release valve to the “Venting” position. Stand clear of the steam as it releases. Wait until the float valve (pressure gauge) drops completely, indicating that all pressure has been released and it is safe to open the lid.
-
Once the lid is safely removed, add 2 cups of your preferred pizza sauce, 1 diced green bell pepper, and 1 sliced red onion to the quinoa mixture. Stir all ingredients thoroughly to combine, ensuring the cooked quinoa, mushrooms, and fresh vegetables are well coated with the flavorful pizza sauce. Replace the lid loosely (do not seal or set to pressure again). Let the mixture sit undisturbed for 5 minutes. This resting period allows the residual heat from the pot to gently soften the added vegetables, enhancing their flavor and texture. After 5 minutes, remove the lid and stir in the entire package of turkey pepperoni. Stir once more to ensure the pepperoni is evenly distributed throughout the casserole.
-
Divide the hot and ready casserole mixture among 6 bowls or as many individual serving dishes as you require for immediate consumption. For those delightful melted cheese pulls, generously top each serving with about 1 cup of shredded mozzarella cheese. Place each individual bowl into the microwave and heat for approximately 1-2 minutes, or until the cheese is perfectly melted, gooey, and bubbly. Garnish with fresh basil or red chili flakes if desired, then serve immediately and enjoy your quick, flavorful, and satisfying Instant Pot Pizza Quinoa Casserole!
-
Important Note for Leftovers: For optimal texture and extended freshness, it is highly recommended to store any remaining pizza quinoa casserole mixture *without* the melted cheese in the refrigerator. Melted cheese can become rubbery when chilled and reheated, affecting the overall quality of the dish. When you are ready to enjoy your leftovers, scoop the desired amount into a microwave-safe bowl. Microwave for 2 minutes to heat through. Stir the mixture, then top with fresh shredded cheese and microwave for an additional 1 minute, or until the cheese is perfectly melted and the casserole is piping hot. This ensures that every serving of leftovers is just as delicious as the fresh batch!
