Ingredients You’ll Need

Here’s what goes into this flavor-packed casserole:
Egg noodles: Wide egg noodles hold the creamy sauce beautifully.
Butter or olive oil: For sautéing the mushrooms, onion, and garlic.
Fresh mushrooms, sweet onion, and garlic: These aromatics create a rich, savory base.
Condensed cream of mushroom soup & milk: For a creamy, velvety sauce.
Seasonings: Garlic powder, salt, and pepper keep the flavors balanced.
Frozen peas: Adds color, sweetness, and a veggie boost.
Monterey Jack cheese: Mild and melty—perfect for casseroles.
Albacore tuna in water: Firm, flaky, and packed with protein.
Ritz crackers & butter: The crunchy topping that’s hard to resist.
Fresh parsley or green onions (optional): For garnish and a little freshness.
Step-By-Step Instructions
Step 1: Preheat the oven to 375°F. Lightly grease a 9x13-inch casserole dish with cooking spray and set it aside.
Step 2: Cook the noodles. Bring a large pot of water to a boil and cook the egg noodles according to package instructions until just al dente. Drain and set aside.
Step 3: Sauté the vegetables. In a large skillet or Dutch oven, melt the butter over medium heat. Add the mushrooms, diced onion, and minced garlic. Sauté for about 5 minutes, or until the mushrooms are tender and the onions are soft.


Step 4: Make the sauce. Reduce the heat to low. Stir in the condensed cream of mushroom soup, milk, garlic powder, salt, and pepper. Mix until everything is well combined.


Step 5: Add peas and cheese. Add the frozen peas to the skillet and simmer for 2–3 minutes. Then, turn off the heat and stir in the shredded Monterey Jack cheese a little at a time until fully melted and smooth.


Step 6: Combine noodles and tuna. Gently fold in the cooked noodles and drained tuna, mixing until everything is evenly coated in the sauce.
Step 7: Assemble the casserole. Transfer the mixture to the prepared casserole dish and spread it out evenly. Cover with foil and bake for 20 minutes.


Step 8: Prepare the topping. While the casserole bakes, mix the Ritz cracker crumbs with the melted butter in a small bowl. Stir until all the crumbs are well coated.
Step 9: Add topping and finish baking. Remove the casserole from the oven and uncover. Sprinkle the buttery cracker mixture evenly over the top. Return to the oven and bake uncovered for another 10 minutes, or until the topping is golden brown and crispy.


Step 10: Garnish and serve. Top with freshly chopped green onions or parsley if desired. Serve warm and enjoy!

Tips for the Best Tuna Noodle Casserole
Here are some helpful tips to take your casserole to the next level:
Don’t overcook the noodles: Boil them just until al dente. Overcooked noodles can turn mushy during baking.
Drain the tuna well: Too much liquid can water down your sauce.
Use block cheese: Shredding cheese yourself results in a creamier sauce (pre-shredded cheese has anti-caking agents that don’t melt as well).
Add extra veggies: Want more color and texture? Toss in frozen mixed veggies or chopped spinach.
Make it ahead: Assemble the casserole up to 24 hours in advance, cover, and refrigerate. Add the cracker topping just before baking.

Serving Suggestions
This tuna noodle casserole is satisfying on its own, but here are a few easy sides that round out the meal beautifully:
- Crisp green salad with a lemon vinaigrette
- Steamed or roasted veggies like broccoli, green beans, or carrots
- Dinner rolls or garlic bread for dipping into all that creamy sauce
- Pickles or olives on the side for a tangy contrast
Want to lighten it up? Serve smaller portions with a veggie-forward salad for a balanced meal.
Storage & Reheating
Store any leftovers in an airtight container in the fridge for up to 4 days. Reheat individual portions in the microwave, or warm larger amounts in a 350°F oven until heated through (cover with foil to prevent drying out).
This dish also freezes well—just skip the topping, freeze, and add the crackers before baking later.

Frequently Asked Questions
Feel free to try sharp cheddar, mozzarella, or even a mix of cheeses. Monterey Jack melts beautifully, but any mild, melty cheese will work.
If you prefer a homemade version, you can make a quick roux-based cream sauce with butter, flour, broth, and cream to replace the condensed soup.
Whether you’re craving comfort food or looking for a freezer-friendly family meal, this Tuna Noodle Casserole is an easy, cheesy classic you’ll want to make again and again.
