From Kitchen to Table

Preheat and Prepare

Start by heating your oven to 375°F. Grease a 9×13-inch baking dish and set it aside. This small step makes serving and cleanup much easier later.

Build the Base

In a large mixing bowl, add the cooked egg noodles, drained and flaked tuna, thawed peas, and finely diced onion. Gently toss everything together so it’s evenly distributed.

Mix the Creamy Sauce

In a separate bowl, whisk together the cream of mushroom soup, milk, Dijon mustard, garlic powder, black pepper, and salt. Take a moment to taste and adjust this is where you can make it feel just right for your family.

Bring It All Together

Pour the sauce over the noodle mixture. Add half of the shredded cheddar cheese and gently fold until everything is coated and creamy.

Transfer and Layer

Spoon the mixture into your prepared baking dish, spreading it evenly. Sprinkle the remaining cheese over the top for that melty finish.

Add the Crunch

Scatter the crushed potato chips evenly over the casserole. Don’t press them down letting them sit lightly on top helps them stay crisp.

Bake Until Golden

Slide the dish into the oven and bake for 15 to 20 minutes, until heated through and the topping turns beautifully golden.

Rest and Serve

Let the casserole cool for a few minutes before serving. This helps everything settle and makes scooping easier.

Simple Ways to Make It Work for You

• Make it ahead: Assemble the casserole earlier in the day, cover, and refrigerate. Add the potato chips just before baking.
• Stretch leftovers: This reheats beautifully and makes an easy next-day lunch.
• Lighten it gently: Use reduced-fat cheese or add extra peas for balance.
• Boost the protein: Stir in an extra can of tuna or a handful of cottage cheese for a quiet protein lift.
• Gluten-conscious swap: Use gluten-free noodles and gluten-free condensed soup.
• Budget-friendly tip: Store-brand tuna, soup, and chips work just as well here.
• Softer topping option: If you prefer less crunch, cover loosely with foil during the first half of baking, then uncover to finish.

These little adjustments let the casserole meet you exactly where you are busy, careful, or simply craving something familiar.
