Essential Ingredients for Your Instant Pot Tuna Noodle Casserole

Gathering your ingredients is the first step to any great meal. This recipe relies on common pantry items and fresh vegetables, ensuring accessibility and ease. Here’s what you’ll need to create this amazing Instant Pot Tuna Noodle Casserole:

• Egg Noodles, Uncooked: The classic choice for tuna casserole, egg noodles provide that perfect soft, chewy texture. We recommend 12 ounces for a generous serving.
• Chicken Broth, Low Sodium: Using low-sodium broth gives you more control over the overall saltiness of the dish, allowing the other flavors to shine through. About 3 cups will create the ideal cooking liquid.
• Light Tuna in Water, Drained (Two 5 oz. Cans): Light tuna is a fantastic source of lean protein. Draining it thoroughly helps prevent a watery casserole. Feel free to use tuna in oil if you prefer a richer flavor, but make sure to drain it as well.
• Small Onion, Diced: Onions add a fundamental aromatic base. Dicing them small ensures they cook down and blend seamlessly into the sauce.
• Celery, Diced (½ cup): Celery contributes a subtle crunch and fresh, savory note, balancing the richness of the casserole.
• Heavy Cream (1 cup): This is where the magic happens! Heavy cream provides the luscious, velvety texture that makes this casserole so comforting.
• Mushrooms, Diced (½ cup): Optional but highly recommended, mushrooms add an earthy depth of flavor. If you’re not a fan, you can omit them or substitute with other diced vegetables like bell peppers.
• Seasonings:
  • Salt (1 teaspoon): Essential for enhancing all the flavors.
  • Garlic Powder (1 teaspoon): Provides a mild, aromatic garlic presence without overpowering the dish.
  • Ground Black Pepper (½ teaspoon): Adds a touch of warmth and subtle spice. Adjust to your preference.
• Unsalted Butter (3 tablespoons): Used for sautéing the vegetables, butter adds richness and helps create a flavorful base.
• Frozen Peas (1 cup): A pop of color and sweetness, peas are a classic addition to tuna casserole. Add them at the end to retain their vibrant green color and slight crispness.
• Olive Oil (1 tablespoon): Used in conjunction with butter for sautéing.
• Sharp Cheddar Cheese, Shredded (2 cups): The star of the show! Sharp cheddar melts beautifully and provides a wonderfully tangy, savory creaminess. Freshly shredded cheese melts better than pre-shredded.

Optional Toppings for Extra Flair:

• Extra Sharp Cheddar Cheese, Shredded: For those who believe there’s no such thing as too much cheese!
• Fresh Parsley, Chopped: A sprinkle of fresh parsley adds a touch of color and a bright, herbaceous finish.

How To Master Instant Pot Tuna Noodle Casserole: Step-by-Step Instructions

Making this casserole in your Instant Pot is incredibly simple. Follow these steps for a perfect, creamy result every time:

1. Sauté the Aromatics: Begin by setting your Instant Pot to the “Sauté” function. Once the inner pot is hot, add the olive oil and unsalted butter. Let the butter melt, then add the diced mushrooms, celery, and onion. Sauté, stirring occasionally, until the onion becomes translucent and the vegetables soften, usually about 3-5 minutes. This step builds a foundational layer of flavor.
2. Build the Liquid Base: Turn off the “Sauté” function. Stir in the chicken broth, salt, garlic powder, and black pepper. Scrape the bottom of the pot with a wooden spoon to ensure no bits are stuck, which helps prevent a “burn” notice.
3. Add the Cream: Pour in the heavy cream and give it a gentle stir to combine with the broth and seasonings.
4. Layer the Noodles: Carefully add the uncooked egg noodles to the pot. Gently spread them into an even layer, but do not stir them into the liquid. Keeping them on top helps prevent sticking and ensures they cook evenly.
5. Add the Tuna: Open and drain your cans of tuna. Crumble the tuna evenly over the noodles. Again, resist the urge to stir. The layering is crucial for proper pressure cooking.
6. Pressure Cook: Secure the lid on your Instant Pot, making sure the sealing ring is properly in place and the vent is set to “Sealing.” Select the “Manual” or “Pressure Cook” setting (depending on your model) and set the cooking time to 3 minutes on High Pressure. Remember that the Instant Pot will take some time (typically 5-10 minutes) to come up to pressure before the actual cooking countdown begins.
7. Quick Pressure Release: Once the cooking cycle is complete, carefully turn the steam release knob to the “Venting” position for a Quick Release. Stand back and allow all the steam to escape. If you notice any mixture starting to come out of the vent, quickly close it and release the pressure in short bursts until all the steam is gone.
8. Cool and Thicken: Once the pressure has fully released and the float valve has dropped, remove the lid. Transfer the inner pot from the pressure cooker to a heat-safe surface. This allows the casserole to cool slightly, which is important for the final consistency.
9. Stir in Peas: Add the frozen peas to the hot casserole and give it a gentle stir. The residual heat will warm the peas perfectly.
10. Melt in the Cheese: While continuously stirring slowly, gradually add the shredded sharp cheddar cheese. Continue to stir until the cheese is fully melted and incorporated, creating a rich, creamy sauce. The casserole will continue to thicken as it cools.
11. Serve and Enjoy: Dish out your delicious Instant Pot Tuna Noodle Casserole. Garnish with additional shredded cheese or chopped fresh parsley, if desired, for extra flavor and visual appeal.

Elevate Your Casserole: The Crunchy Topping Option

While this Instant Pot Tuna Noodle Casserole is delightful on its own, adding a crispy topping can take it to the next level. If you love that golden-brown, crunchy texture, here’s how to achieve it:

1. Prepare for Broiling: Once your casserole is cooked in the Instant Pot and you’ve stirred in the peas and cheese, transfer the entire mixture into a baking dish suitable for broiling (approximately 9×13 inches works well).
2. Craft the Topping: In a small bowl, combine about ½ cup of panko breadcrumbs, 1 tablespoon of melted unsalted butter, and ½ cup of grated Parmesan cheese. Mix well until the breadcrumbs are evenly coated.
3. Broil to Perfection: Sprinkle this savory topping evenly over the casserole in the baking dish. Place the dish under a preheated broiler for just a few minutes, keeping a close eye on it. Broil until the topping is golden brown and deliciously crispy. This usually takes 2-4 minutes, but broiler temperatures vary, so watch carefully to prevent burning.

Instant Pot Tuna Casserole: Your Questions Answered

As with any recipe, you might have a few questions. Here are some common queries and helpful answers to ensure your Instant Pot Tuna Noodle Casserole is a success:

• Help, I’m getting the “burn” message! What should I do?

  The “burn” message is usually triggered when food is sticking to the bottom of the Instant Pot. This often happens if there isn’t enough liquid, or if the noodles/tuna were stirred into the broth, causing them to settle at the bottom. To prevent this, ensure you always follow the layering instructions carefully, placing noodles and tuna on top of the liquid without stirring. Also, make sure you scrape the bottom thoroughly after sautéing to remove any stuck-on bits. If you get a burn message, release pressure, open the pot, check the bottom, and carefully scrape if needed before trying to resume cooking with more liquid if necessary.

• Will this stay good in the fridge if there are leftovers? Wait… you have leftovers??

  It’s true, leftovers of this delicious Instant Pot Tuna Noodle Casserole are a rare sight! However, if you do find yourself with some, rest assured it stores beautifully. Simply transfer the cooled casserole to an airtight container and refrigerate for up to 3-4 days. It reheats well in the microwave or on the stovetop with a splash of milk or broth to restore its creaminess.

• Can I use water instead of chicken broth?

  You certainly can use water as a substitute for chicken broth in a pinch. However, be aware that using water will result in a less flavorful casserole. Chicken broth adds a significant depth and savory richness that water simply cannot replicate. For the best possible taste, we highly recommend sticking with low-sodium chicken broth.

• Can I use different types of pasta?

  While egg noodles are traditional for tuna casserole, you can experiment with other small-shaped pasta like elbow macaroni or medium shells. The key is to adjust the cooking time accordingly, as different pasta shapes and sizes may require slightly different pressure cooking times. Generally, shorter pasta like macaroni cooks in 2-3 minutes under pressure, similar to egg noodles.

• Can I add other vegetables?

  Absolutely! This recipe is very adaptable. Feel free to add other quick-cooking vegetables like diced bell peppers (sauté them with the onions and celery), or stir in cooked corn or green beans with the peas at the end. Just be mindful not to overfill your Instant Pot.

• Can I make this dairy-free or gluten-free?

  For a dairy-free version, you could try using a plant-based heavy cream substitute and dairy-free shredded cheese. For gluten-free, use gluten-free egg noodles (ensure they are suitable for pressure cooking, as cooking times might vary slightly) and ensure your broth is gluten-free. Always check labels to confirm ingredients meet your dietary needs.
