Ingredients for kraft macaroni and cheese tuna casserole
Pantry staples meet comfort food magic—just six ingredients transform Kraft into restaurant-worthy crispy casserole goodness.
| Ingredient | Amount | Notes |
|---|---|---|
| Kraft Macaroni and Cheese Powder 🧀 | 2 boxes | Regular or extra cheesy flavor |
| Milk 🥛 | 4 cups | Whole milk preferred |
| Canned Tuna in Water 🐟 | 2 cans | Drained, flaked preferred |
| Frozen Peas 🌽 | 1 cup | Thawed, no need to drain |
| Butter 🧈 | ½ cup | Unsalted, softened for topping |
| Panko Breadcrumbs 🍞 | 1 ½ cups | Plain or seasoned works |
| Shredded Cheddar Cheese 🧀 | 1 cup | Extra sharp for best flavor |
| Garlic Powder 🧄 | 1 tbsp | Freshly ground preferred |
| Dried Parsley Flakes 🌿 | 1 tbsp | For fresh herb brightness |
| Salt 🧂 | ½ tsp | Adjust to taste |
| Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Heavy Cream 🥛 | ¼ cup | For extra creaminess |
The Kraft boxes are the secret weapon here—extra cheesy flavor gives that nostalgic punch, but regular works too. Walmart or Target usually have them on sale in bulk, which is perfect since you'll need two. The tuna should be flaked, not chunky—I grab the Wild Planet brand for better texture. Frozen peas are a must (no canned—they get mushy). For the breadcrumbs, Panko is non-negotiable—it stays crispy while regular breadcrumbs turn soggy. If you can't find Panko, Trader Joe's sells a great alternative in their freezer section.
No Panko? Toast regular breadcrumbs in the oven at 350°F for 5 minutes first—they'll crisp up better. Swapping tuna? Chicken or shrimp works too, but tuna's that classic casserole flavor. Short on cheese? Add a splash of milk to the dry mix for extra creaminess. The garlic powder and parsley flakes are easy to find in the spice aisle—Penzeys has great quality if you want to splurge, but the store brand is fine. For the crispy topping, butter matters more than cheese—don't skip it, even if you're watching calories.
This casserole reheats beautifully—350°F for 20 minutes until bubbly. Leftovers keep for 4 days in the fridge, but honestly, it disappears fast. The breadcrumb topping gets crispy again when reheated, so it's worth making extra. For meal prep, portion into individual baking dishes before baking—just pop them in the oven when ready. Freezes well too (3 months) if you want to make it ahead for a lazy weeknight.

Step-by-step instructions for Kraft macaroni and cheese tuna casserole
Here's how to create a comforting, crispy-topped casserole that brings together creamy macaroni and cheese with flaky tuna and vibrant peas.
Prepare the Macaroni and Cheese Base
In a large pot, bring the 4 cups milk to a gentle boil over medium heat. While the milk heats, prepare the 2 boxes Kraft Macaroni and Cheese Powder according to the package instructions—typically this means whisking the powder into the hot milk until completely dissolved. Stir in the 1 cup frozen peas and let the mixture simmer for 5 minutes until the macaroni is tender and the sauce has thickened slightly. You'll know it's ready when the sauce coats the back of a spoon and the peas are heated through.
Remove the pot from heat and stir in the 1 cup shredded cheddar cheese until fully melted and smooth. This step creates the rich, cheesy foundation that holds everything together. For extra creaminess, whisk in the 0.25 cup heavy cream now while the mixture is still warm—this ensures it blends seamlessly without clumping.
Flake and Season the Tuna
While the macaroni and cheese base cooks, drain the 2 cans canned tuna in water thoroughly and flake it into a medium bowl using a fork. Add the 1 tbsp garlic powder, 1 tbsp dried parsley flakes, 0.5 tsp salt, and 0.5 tsp black pepper. Gently mix everything together until the tuna is evenly coated with the seasonings. The goal here is to distribute the flavors without breaking the tuna into tiny pieces—you want visible flakes that stay intact when folded into the casserole.
Taste the tuna mixture and adjust the seasoning if needed. Remember, the tuna will absorb some of the flavors from the macaroni and cheese base, so don't over-salt now. Set the seasoned tuna aside until ready to combine with the macaroni and cheese.
Assemble the Casserole
Transfer the macaroni and cheese mixture to a 9x13-inch baking dish, spreading it evenly across the bottom. Use a spatula to create gentle swirls in the sauce, which will help distribute the tuna more attractively later. Gently fold the seasoned tuna flakes into the macaroni and cheese, being careful not to overmix. You want the tuna to be evenly distributed but still visible throughout the dish. The peas will add pops of color and texture to each bite.
Sprinkle the 1.5 cups panko breadcrumbs evenly over the top of the casserole, pressing down lightly with the back of a spoon to help them adhere. This step is crucial for achieving that crispy breadcrumb crown you're aiming for. The panko will soak up some of the moisture from the casserole during baking, creating a golden, crunchy topping.
Bake to Crispy Perfection
Preheat your oven to 375°F and let it come to temperature while you prepare the casserole. Melt the 0.5 cup butter in a small saucepan over low heat, then brush this melted butter evenly over the panko breadcrumb topping. The butter will help create a rich, golden-brown crust while adding extra flavor. Place the baking dish on the middle rack of your oven and bake for 20-25 minutes until the top is deep golden brown and the edges are bubbling.
To check for doneness, look for a crispy, golden-brown crust on top that's slightly puffed up. The casserole is ready when the internal temperature reaches 165°F and the breadcrumbs are crispy to the touch. Let the casserole rest for 5 minutes before serving—this allows the top to set slightly and makes it easier to cut clean slices.
Serve with Confidence
Use a large spatula to carefully transfer the casserole to a serving platter. The crispy breadcrumb topping should hold together beautifully, giving you that satisfying crunch with every bite. Serve immediately while the casserole is hot, as the crispiness will start to soften as it cools. Each forkful should deliver creamy macaroni and cheese, tender tuna flakes, sweet peas, and that irresistible crunch from the breadcrumb topping.
For extra presentation, garnish with additional dried parsley flakes or a sprinkle of black pepper. This dish tastes even better the next day, so consider making extra for leftovers—just reheat in the oven at 350°F until warmed through, covered with foil to prevent the breadcrumbs from drying out.
Pro Tips For Making Kraft Macaroni And Cheese Tuna Casserole
- Drain Tuna Well: That waterlogged tuna is the fastest way to turn your casserole into a soggy mess. Dump the can into a colander, give it a quick rinse, then let it drain for 2-3 minutes—even if you’re tempted to skip it. Trust me, the texture difference is night and day, and you won’t regret the extra 60 seconds.
- Cook Pasta Al Dente: Kraft’s powdered cheese relies on starch for that creamy glue, so overcooking the macaroni turns your casserole into a gluey brick. Pull the pasta when it’s just firm to the bite—about 1 minute less than the box says. Undercooked pasta finishes in the oven, but mushy pasta? No coming back from that.
- Toast the Peas: Frozen peas straight from the bag taste like they’re still in the pod. Microwave them for 30 seconds first, then drain any released water—this concentrates their flavor and prevents them from turning to mush under the broiler. (Yes, even if you’re lazy, do this.)
- Mix in Butter Last: Stirring cold butter into the hot macaroni mix at the end creates pockets of richness that melt into the casserole as it bakes. If you add it early, you’ll end up with a greasy, separated sauce. Think of it like buttering toast—timing matters more than you’d guess.
Serving suggestions for this kraft macaroni and cheese tuna casserole
Classic Presentation
Serve this casserole straight from the baking dish onto a large wooden board or platter for that rustic, comforting vibe. The golden breadcrumb topping looks stunning when presented this way, and it makes the dish feel special without extra effort.
I like to add a few fresh parsley leaves around the edges for a pop of color that contrasts beautifully with the creamy yellow of the mac and cheese. 🌿
Side Salad Pairing
A crisp arugula salad with lemon vinaigrette cuts through the richness perfectly. Toss 4 cups baby arugula with 2 tbsp olive oil, 1 tbsp lemon juice, ½ tsp salt, and ¼ tsp black pepper.
The peppery bite balances the creamy casserole, and the bright acidity cleanses your palate between bites. For extra protein, add ½ cup cherry tomatoes and ¼ cup crumbled feta cheese.
Bread Basket Addition
No casserole is complete without warm bread to soak up those extra bites of cheesy goodness. I recommend a crusty French baguette or garlic bread—both work perfectly.
For a quick version, brush slices with melted butter, sprinkle with garlic powder, and toast in the oven at 375°F for 5 minutes. The warm, buttery bread contrasts beautifully with the crispy topping. 🥖
Dipping Sauce Ideas
For guests who love extra flavor, serve with a small bowl of tartar sauce or spicy mayo. Mix ½ cup mayonnaise with 1 tbsp Dijon mustard, 1 tbsp lemon juice, 1 tbsp finely chopped dill, and ½ tsp Worcestershire sauce for a classic tartar sauce.
For heat lovers, add ½ tsp hot sauce or 1 tsp sriracha to the mayo. The sauce adds a fresh, tangy contrast to the rich casserole.
Family-Style Serving
This casserole is perfect for family-style dining—just transfer it to a large platter and let everyone serve themselves. Use a large metal spatula to slice through the crispy topping cleanly.
For extra fun, arrange small bowls of extra breadcrumbs and grated Parmesan cheese on the table so guests can customize their portions. The interactive element makes it feel like a restaurant experience at home. 🍽️
Leftovers Reinvented
Turn cold leftovers into tuna casserole croquettes by mixing shredded casserole with 1 egg and ¼ cup panko breadcrumbs, then pan-frying until golden.
For a deconstructed version, layer leftover casserole in a ramen bowl with quick-pickled veggies (thinly sliced cucumbers + rice vinegar) and a soft-boiled egg for a modern twist. The crispy topping can also be crumbled over avocado toast for a brunch upgrade.

Frequently asked questions
Can I use a different type of pasta instead of Kraft macaroni?
Elbow macaroni is traditional, but penne or farfalle work beautifully too. For a gluten-free option, swap in gluten-free pasta and use a dairy-free cheese sauce. Just note that cooking times may vary slightly—always check the package instructions for your pasta choice.
How do I make this dish dairy-free?
Replace the Kraft Macaroni and Cheese with a dairy-free boxed mac and cheese (like Daiya or Follow Your Heart). Use unsweetened almond milk or coconut milk instead of regular milk, and swap the cheddar for vegan shredded cheese. The tuna and breadcrumb topping will still work perfectly with these adjustments.
Can I add other vegetables besides peas?
Yes! Try adding corn (½ cup frozen), diced bell peppers (½ cup), or spinach (1 cup, wilted first). For extra heartiness, stir in diced carrots or zucchini with the peas. Just be mindful of moisture—don't overdo it, or the breadcrumb topping may get soggy.
Why did my breadcrumb topping get soggy?
This usually happens if the casserole isn't baked long enough or if too much liquid is present. To fix it, bake at 375°F for 5-10 extra minutes until the top is crispy. For next time, press the breadcrumbs down firmly before baking, and consider adding 1 tbsp cornstarch to the panko to absorb extra moisture.
Can I make this casserole ahead of time?
Yes! Assemble the casserole (without baking) up to 24 hours ahead and refrigerate. When ready to bake, cover with foil and bake at 375°F for 30-35 minutes (add 5-10 extra minutes if it was refrigerated). For freezing, bake the casserole first, then cool completely, wrap tightly in foil, and freeze for up to 3 months. Reheat at 350°F until warmed through.
