🍯 Why This Recipe Works
- It's affordable. We call it "poor man's tuna casserole," and I mean, boxed macaroni is cheap. I think this entire pot costs me less than $7 to make, so I can see how the name might stick. But actually, the name came from my childhood when we ate boxed mac and cheese and Crispy Fried Tuna Patties. My mom called that "poor man's dinner" and it's a nostalgic meal we've eaten ever since.
- It's easy to make. If you're looking for a simple one pot meal, this macaroni and cheese with tuna and peas recipe really hits the spot. I love it as a Lazy Sunday Dinner Idea.
- The whole family can love it. My son may pick out the peas on his plate, but this is a recipe that everyone enjoys to eat. Cheesy, savory, meaty and delicious.
🥘 Ingredients
Ingredient Notes:
Boxed Macaroni and Cheese- You can use any brand to make this recipe, but I find that Walmart's Great Value Thick and Creamy Mac and Cheese is our favorite.
Frozen Peas- You will want to add in some frozen peas to the plate for added color. If desired, you can use canned sweet peas, but drain them and add them in at the very end.
Canned Tuna- Adding in canned tuna is what gives us that great taste and adds an affordable protein to the dish. If you still have cans of tuna, try our Spicy Tuna Sandwich and Air Fryer Tuna Melt.
Ritz Crackers- This is an optional topping, but I highly recommend it. The buttery crispness just adds so much to the recipe as far as flavor depth and textures go. (We also love this on top of our Chicken Divan Casserole).

- Adjusting Ingredients- If preferred, substitute frozen peas with canned peas by draining and rinsing them before use. Add them to the dish just before serving for added texture and flavor.
- Crumb Topping Option- For an extra touch of flavor and crunch, try topping your stovetop tuna casserole with crushed Ritz cracker crumbs. Experimenting with toppings can elevate the dish and cater to different tastes.
- Macaroni Variations- Experiment with different brands and types of macaroni and cheese, including Kraft, store brands, "creamy" versions, and various shapes. Each variation offers unique flavors and textures, allowing you to customize the dish according to your preferences.
💭 Recipe FAQs
Traditionally, tuna noodle is a dish with noodles, cheese, cream of soups, tuna, and a veggie (usually peas). The toppings (if any) can vary from crushed potato chips to breadcrumbs. This dish is very simple with boxed macaroni and cheese, tuna, cream of mushroom, peas, and onion.
I usually serve the dish alone as-is but sometimes I enjoy serving it up with more veggies like a simple green garden salad or steamed broccoli. Sticking with this that tastes great with cheddar cheese is a pretty safe bet for getting a good tasting meal on your plate.
To heat this dish you can simply place a serving on a plate in the microwave for 1-2 minutes or you can reheat it on the stovetop. To avoid it drying out consider adding a tablespoon of butter or a dash of milk to keep the mix hydrated.
