Sometimes, the last thing you want is to turn on the oven, especially on those sticky, tired evenings. This no-bake tuna casserole is exactly the kind of meal that feels like a warm hug without the oven’s heat blasting your kitchen. It’s quick, creamy, and cozy, wrapping tender pasta and savory tuna in a cheesy sauce that’s ready in under half an hour.
One night, I remember rushing home, the heat outside making me dread cooking, but this dish was a lifesaver. I cooked the pasta, mixed everything in a bowl, and just like that, dinner was done. The mixture of creamy mushroom soup and mayo made the sauce so smooth, and the peas added a little pop of color and sweetness. I wasn’t paying full attention at one point—maybe distracted by a text or the TV—and I mixed it just a bit too vigorously, which ended up making the casserole a little chunkier than usual. But honestly? It tasted just as good, if not better. Sometimes those little imperfections turn into new favorites.

A quick and easy no-bake tuna casserole that combines creamy sauce, tender pasta, and savory tuna for a comforting meal without turning on the oven.
Ingredients
8 ounces elbow macaroni
1 (10.5 ounce) can condensed cream of mushroom soup
1/2 cup mayonnaise
1/2 cup milk
1 cup shredded cheddar cheese
1 (5 ounce) can tuna packed in water, drained

Add the shredded cheddar cheese, drained tuna, thawed peas, chopped onion, garlic powder, black pepper, and dried parsley flakes to the bowl. Mix well to combine all ingredients evenly.
Add the cooked and cooled macaroni to the mixture. Gently fold until the pasta is fully coated with the sauce and all ingredients are well distributed.
Transfer the mixture to a serving dish or individual bowls. The casserole is ready to serve immediately or can be chilled in the refrigerator for 30 minutes to 1 hour for a cooler dish.

Kitchen Notes
This recipe doesn’t call for any special equipment—just a pot for your pasta and a big bowl for mixing. I usually serve this with a simple green salad or some crusty bread to round out the meal. If you want to switch things up, you could try swapping the peas for corn or diced bell peppers, though I haven’t tested those variations thoroughly. Some people like adding a dash of hot sauce or a sprinkle of paprika on top for a little kick. You could also fold in a handful of fresh herbs if you have them on hand—parsley is a natural fit. Just remember, it’s meant to be easy and comforting, so don’t stress about perfect measurements or fancy tweaks.
FAQ
Can I make this ahead of time? Yes, it actually holds up well chilled in the fridge for an hour or two before serving, which makes it handy for meal prep.
Is it safe to eat cold? Absolutely. This casserole is delicious both warm and chilled, so it’s up to your preference.
Can I use fresh tuna instead of canned? You could, but you’d want to cook it first and flake it finely. The canned tuna provides that classic flavor and texture that works best here.
What if I don’t have cream of mushroom soup? You might try cream of celery or chicken soup instead, but it will change the flavor profile a bit.
