This creamy tuna pasta bake is a weeknight staple in my kitchen whenever we crave something filling comforting and hands-off. The sauce coats every bite of pasta and the bubbling cheesy top just begs for that first scoop. With plenty of veggies folded in and no fuss steps this oven-baked classic is a lifesaver for busy nights.
When I made this for my neighbor during a move she asked for the recipe and now it is in her family’s weekly dinner rotation too. It is the dinner that disappears quickest at my house especially after chilly soccer practices.
Ingredients
- Penne or fusilli pasta: adds bite and holds sauce well Choose bronze-cut varieties for the best texture
- Canned tuna in water: for lean protein Opt for dolphin-safe sustainably sourced brands
- Heavy cream: gives a lush base Pick pure cream with no thickeners
- Whole milk: lightens the sauce without making it thin
- Grated cheddar cheese: for sharp cheesiness Go for mature cheddar if you enjoy bolder flavor
- Grated mozzarella cheese: brings meltiness Use whole block mozzarella you grate yourself for best texture
- Cream cheese: makes the sauce ultra creamy and smooth
- Unsalted butter: controls salt levels and adds richness
- Small onion finely chopped: builds a sweet flavor base Choose onions with tight papery skin for freshness
- Garlic: brings aromatic depth Use fat firm cloves for the best result
- Frozen peas: offer color and sweetness Look for bright green peas that are not icy or clumped
- Sweetcorn canned or frozen: for a pop of crunch Select kernels that look plump and golden
- All-purpose flour: thickens the sauce
- Dijon mustard: brightens and lifts the creaminess
- Dried thyme: adds gentle herby background
- Dried parsley: brings a fresh finish
- Salt and black pepper: for essential seasoning
- Breadcrumbs: create a crispy topping Try to use fresh breadcrumbs for lighter crunch
- Grated Parmesan cheese: sharpens the crust Look for genuine Parmesan not Parmesan blend
- Olive oil: helps the topping brown evenly Extra virgin olive oil gives the best flavor
Instructions
- Preheat the Oven:
- Set your oven to 200 degrees Celsius or 390 degrees Fahrenheit and grease a medium baking dish with a light layer of oil or butter. This prevents sticking and helps the bake come out easily.
- Cook the Pasta:
- Bring a large pot of salted water to a boil. Add your chosen pasta and cook until just al dente usually a minute less than package directions. Drain thoroughly but do not rinse to help the sauce cling later.
- Sauté the Aromatics:
- Place a large skillet over medium heat and melt the unsalted butter. Add chopped onion and cook gently for about four minutes till translucent and tender. Toss in the minced garlic and stir for another minute until fragrant but not browned.
- Build the Creamy Sauce:
- Sprinkle flour evenly over the onion mixture and stir constantly letting it cook for a minute. Gradually pour in the heavy cream and whole milk whisking non-stop so the mixture stays smooth. In about three minutes the sauce should be thick enough to coat the back of a spoon.
- Add Flavor Layers:
- Stir in the cream cheese Dijon mustard dried thyme and dried parsley. Mix until cream cheese melts completely. Taste and season with salt and freshly cracked black pepper.
- Combine the Goodies:
- Add the flaked tuna drained peas and sweetcorn along with half the grated cheddar and mozzarella. Stir until everything is well distributed in the thickened sauce.
- Mix Pasta and Sauce:
- Tip the drained pasta right into the creamy sauce. Toss thoroughly so every piece of pasta gets coated. Pour the whole mixture into your greased baking dish and level the top gently with a spatula.
- Layer and Top:
- Scatter the remaining cheddar and mozzarella over the pasta then sprinkle all the grated Parmesan. In a separate bowl toss the breadcrumbs with olive oil then spread this mixture evenly over the whole dish for a golden crisp topping.
- Bake to Perfection:
- Transfer the dish to the hot oven and bake uncovered for twenty to twenty five minutes. The top should be bubbling and golden crisp at the edges. Watch carefully during the last minutes so the topping does not burn.
- Cool and Serve:
- Remove from the oven and let the pasta bake rest for five minutes. This lets the sauce settle so you get neat creamy portions when you scoop it onto plates.

I love how the tiny bits of crispy Parmesan topping give every forkful a bit of savory crunch while the hidden peas and corn keep it light and lively. The smell of this bubbling away in the oven always brings everyone into the kitchen early begging for just a taste off the spoon.
Storage Tips
This bake keeps well in an airtight container in the fridge for up to three days. To reheat cover with foil and warm in a medium oven until heated through or use the microwave for quick portions. Add a splash of milk or cream if the sauce thickens up too much overnight.
Ingredient Substitutions
Feel free to swap out penne for rigatoni or shells and use gluten-free pasta for dietary needs. You can replace tuna with cooked salmon or even chicken for a different twist. If you are low on cream cheese ricotta or even mascarpone makes a lovely substitute in the sauce.
Serving Suggestions
All you really need is a fresh green salad on the side. For a dinner party sprinkle with fresh chives and serve with a chilled glass of white wine. Leftover pasta bake makes a cozy lunch packed in a thermos or simply reheated.

Success Stories
I once made double for a busy book club and everyone went back for seconds even with dessert waiting. Another friend texted days later asking for tips on making it dairy free so her whole family could enjoy it.
Freezer Meal Conversion
Assemble the dish right to the point of baking then wrap tightly and freeze for up to two months. Bake straight from frozen at a slightly lower temperature and add about ten extra minutes to the baking time until the center is piping hot.
