This broccoli and tuna pasta bake is exactly what you want on a regular evening: simple, budget-friendly ingredients you probably already have, fresh broccoli, and a creamy, cheesy sauce that brings it all together.

I make this kind of cheesy pasta bake all the time -ย like really often. Broccoli and tuna pasta bake, Oven-Baked Salmon Pasta without Cream, or Chorizo Pasta Bake - my kids, and definitely my husband, love them. Pasta and cheese are probably the two ingredients no one can say no to.
If you've tried a few of my pasta dishes already - like Salmon Crรจme Fraiche Pasta or One Pot Lemon Ricotta Pasta - this one fits right in: simple, creamy, and good for weeknight dinners.

Recipe ingredients

Pasta: Use any short pasta you like. I had fusilli, but penne, macaroni, or something similar works just as well. Try the Tuna Mac and Cheese or the Creamy Tuna Carbonara, too.
Tuna: I use 2 cans of tuna in water (about 5-6 oz / 140-170 g each). Drain well before adding.
Broccoli: Use the florets and the peeled, chopped stem. The stem adds flavor and texture without any waste.
Cheese: Cheddar, Gouda, Gruyรจre, Fontina, or any good-melting, flavorful cheese you like. Half goes in the sauce, and the rest gets sprinkled on top before baking.
Dairy: Heavy cream, milk, and a bit of sour cream. You can also use cream cheese if you don't have sour cream.

How to make broccoli and tuna pasta bake?
Preparations: Cook the pasta al dente, drain it, and return it to the pot. While the pasta cooks, chop the ingredients and make the tuna pasta sauce.

Step #1: Sautรฉ the onion until translucent, then stir in the garlic.

Step #2: Add broccoli, cream, milk, and seasoning. Cook, covered, for 5 minutes, stirring occasionally. Add sour cream and adjust the taste.

Step #3: Combine pasta, sauce, drained tuna, and ยฝ of the grated cheese in the large pasta pot, then transfer the mixture to the buttered baking dish.

Step #4: Bake for 15-20 minutes until the cheese is golden and melty.
Variations
Vegetables: Use peas, carrots, peppers, or zucchini instead of broccoli.
Protein swap: For a completely different flavor, swap cooked chicken for tuna.
Quick version: Skip baking, combine pasta with the sauce and cheese, and serve immediately for a stovetop meal. Another super quick pasta dish is the Mac and Cheese Without Milk.
Tips
- Don't overcook the pasta in the boiling water - it will finish cooking in the oven.
- Chop the broccoli stem finely so it cooks evenly with the florets.
- Taste and adjust the seasoning in the sauce before baking.
- Use a mix of cheeses if you have several leftover scraps.
Store and reheat
Store leftovers in an airtight container in the fridge for 3-4 days.
Freezing: Let the pasta bake cool completely. Transfer to an airtight container and freeze for up to 2-3 months. Thaw in the fridge overnight before reheating.
Reheat in the oven at 175 ยฐC / 350 ยฐF for 10-15 minutes until warmed through. You can also microwave individual portions, stirring halfway through.

- Cheese: Cheddar, Gouda, or any good-melting, flavorful cheese you like is okay.
