    • The Perfect Weeknight Meal! - This creamy tuna pasta broccoli bake is that perfect mix of pantry staples, a good amount of veggies so you can call it healthy, but still with that cheesy comfort food goodness! It cooks all in one pot and is quick to throw together on a busy weeknight!
    • NO Condensed Soup! - I love baked pastas and comforting casseroles! They feel like mom's cooking in the 80's to me! But condensed soup, no thanks! And you don't need it, this creamy sauce is made with ricotta and Parmesan cheese, a bit of real cream, and some of the starchy cooking liquid from the pasta. Real ingredients, not from a can!
    • Fast and Easy! - Sometimes it feels like adding the protein to dinner is the hardest part. I forgot to thaw chicken, or I just didn't get to the store for something fresh. Meatless meal nights are great, but a can of tuna can really come to the rescue!

    • Tuna Broccoli Pasta Bake

    Ingredients & Substitutions

    Labeled ingredients for Tuna Broccoli Pasta Bake.
    • Large Pasta Shells - I love using shells in a pasta bake because all those little nooks and crannies get filled with sauce, tuna and veggies. You could substitute any short pasta, like medium shells, bowties, penne or macaroni.
    • Broccoli - My favorite kid-friendly vegetable! The broccoli cooks right along with the pasta so there's no need to cook it separately. Frozen broccoli is fine too, the instructions are the same.
    • Frozen Peas - A handful of peas just adds a little extra nutrition!
    • Ricotta and Parmesan Cheese - Like in lasagna, the cheese is the main component of the sauce as the pasta bakes.
    • Cream - Real heavy cream adds that touch of richness to the sauce and eliminates the need for "cream of" canned soup!
    • Tuna - A pantry staple! A simple can of tuna is such a great way to add protein to a dish. You could also substitute cooked skillet chicken breast or ham (Easter ham or even chopped deli ham) in this dish.
    • White Cheddar and Corn Flakes - The topping is always the best part! White cheddar cheese for that melty gooeyness and the buttered corn flakes for that slightly sweetened crunch! Regular cheddar, provolone or mozzarella are also fine. You could sub crushed Ritz crackers or bread crumbs, but I love the flakes!

    Instructions

    The pasta and broccoli cook together and then it bakes up creamy and delicious all in one pot!

    Large pasta shells and chopped broccoli boiling together to finish at the same time.

    Step 1 - Preheat your oven and bring a large pot of salted water to a boil.

    Cook the pasta shells for a total of 10 minutes. In the final 3 minutes of cooking, add the chopped broccoli to boil with the pasta.

    So the pasta will cook 7 minutes by itself and then 3 more minutes together with the broccoli for a total of 10 minutes and finish at the same time.

    Adding tuna, cheese and cream to the drained pasta and broccoli.

    Step 2 - Reserve 1 cup of the cooking liquid before draining (a coffee cup works great to scoop it out).

    Don't skip this step! That starchy cooking liquid is needed to make the sauce and keep your casserole from drying out!

    Drain the pasta and broccoli and return to the pot. Add in the cooking liquid, peas, ricotta and Parmesan cheese, cream, tuna and sprinkle with salt and pepper.

    Mixing the tuna broccoli casserole together before adding the topping.

    Step 3 - Mix until well combined. You can bake it in the same pot, or transfer it to a 9x12 or round casserole dish.

    Step 4 - Top your tuna broccoli casserole with shredded cheese, then with the buttered cornflakes and bake at 400° for 15 to 20 minutes!

    Recipe Tips

    • Make Ahead Instructions - Yes you can make this broccoli tuna casserole ahead of time! Just follow all instructions, but don't bake it. Cover well and store in the fridge for a day or two. Before baking, let it sit on the counter about an hour to come to room temperature. Cover it with tinfoil in the first 15 minutes of baking to keep it from drying out. Then cook without the foil until it is heated through. The cooking time may take a bit longer so just check to make sure it's hot!
    • Don't skip the cooking liquid! - Pulling out some of that starchy liquid that the pasta has cooked in is one of the great techniques of sauce making! Just dunk a measuring cup or coffee cup into the water just before you drain it. It thins the ricotta cheese a bit and keeps your pasta bake from drying out in the oven. If you did forget and pour it down the drain, add some extra cream or milk to give the dish a bit more liquid.
    • Storage - Store leftovers in the fridge for 3 days. Leftovers can be portioned and frozen but may not be quite as fresh when thawed.
    • Stir in a splash of milk or cream when reheating leftovers. - Leftovers are great for lunch and can be reheated in the microwave or on the stovetop. A bit of extra liquid keeps if from being dry.

    Recipe FAQs

    Can I use frozen broccoli for this recipe?

    Yes! Both fresh OR frozen peas and broccoli will work just fine. If using frozen broccoli, make sure it's chopped into bite sized pieces and just throw it in with the boiling pasta for the last minute of cooking.

    Can I increase or change up the protein?

    Yes, you can use 2 small cans of tuna or 1 large to add protein. You can also use this recipe with different meats including fully cooked chicken, Italian sausage, bacon or ham.

    Can I skip the cornflake topping?

    Yes, if it isn't your thing, just leave off the cornflake topping. You can choose to add buttered breadcrumbs or crushed ritz crackers instead, or just the cheese as the topping.

    Ingredients

    • 1 pound pasta - large shells (reserve 1 cup of the cooking liquid before draining!)
    • 1 teaspoon kosher salt added to the boiling water
    • 3 cups broccoli (fresh or frozen) chopped small
    • ½ cup frozen peas
    • 1 cup ricotta cheese
    • ½ cup Parmesan Cheese shredded
    • ¾ cup heavy cream
    • 12 oz can tuna, drained (preferably solid, not chunk - break it up with a fork)
    • ½ teaspoon kosher salt
    • 6 grinds fresh black pepper
    • 1 cup white cheddar shredded (or sub regular cheddar, provolone, or mozzarella)
    • 2 cups corn flakes cereal
    • 1 Tablespoon butter melted

    Instructions

    • Preheat oven to 400°. In a large pot, boil water and then add 1 teaspoon of salt. Cook pasta shells according to package instructions, about 10 minutes. In the final 3 minutes of cooking, add the chopped broccoli to boil with the pasta. So the pasta will cook 7 minutes by itself and then 3 more minutes together with the broccoli for a total of 10 minutes and finish at the same time.
    • Reserve 1 cup of the cooking liquid before draining (a coffee cup works great to scoop it out and add to a measuring cup). Drain the pasta and broccoli and return to the pot. Add in the cooking liquid, peas, ricotta and Parmesan cheese, cream, and tuna. Sprinkle with the salt and pepper and then mix very well with a spoon or spatula to combine.
    • You can bake it in the same pot, or transfer it to a 9x12 or round casserole dish. Melt the butter in a bowl in the microwave and then mix with the cornflakes. Top pasta bake with shredded cheddar cheese, then with the buttered cornflakes. Bake for 15 to 20 minutes, until the casserole is warmed through and the flakes are browned a bit. Allow to sit a few minutes before serving.

    Notes

    Don't skip the cooking liquid! - Pulling out some of that starchy liquid that the pasta has cooked in is one of the great techniques of sauce making!  Just dunk a measuring cup or coffee cup into the water just before you drain it and measure out 1 cup.  It thins the ricotta cheese a bit and keeps your pasta bake from drying out in the oven.  If you did miss it and pour it down the drain, add some extra cream or milk to give the dish a bit more liquid.

      This is a great tuna casserole--very delicious and very healthy. My Mom would crush the corn flakes, so that's what I did. It seemed to blend better with the melted butter for me.
