Kraft Mac And Cheese Tuna Casserole Recipe: Nostalgic One-Dish Comfort

Sometimes the most comforting meals come from the simplest ingredients. This one-dish creation combines nostalgic flavors with modern convenience, delivering warmth in every bite without complicated techniques.

I developed this recipe for busy weeknights when you need something filling and familiar. The Kraft base provides that classic creamy texture, while tuna adds protein to create a balanced, satisfying meal the whole family will love.

The beauty lies in its adaptability—use what you have on hand, adjust seasonings to taste, and let the oven do most of the work. You’ll end up with a bubbling, golden casserole that tastes like home.

Perfect for potlucks or quiet evenings in, this dish proves that great comfort food doesn’t need to be complicated.

Ingredients for Kraft Mac and Cheese Tuna Casserole

Comfort starts with a box of nostalgia and a few pantry staples for this one-dish wonder.

The Kraft base is non-negotiable here—standard blue box delivers that exact childhood flavor memory (the powdered cheese just hits different). I grab mine from any major grocery store—no need for fancy brands. For the tuna, chunk light in water works great, but solid white albacore adds a nicer texture if you’re feeling fancy. Just drain it really well so your casserole isn’t watery.

No milk on hand? Heavy cream thinned with water at a 1:1 ratio works. Swap the peas for diced carrots or corn (frozen works in a pinch). The cheese sauce can handle extra mix-ins—diced bell peppers or celery add nice crunch. If you’re out of Dijon, yellow mustard at half the amount gets you close enough.

Assemble and bake immediately, or prep ahead and refrigerate up to 24 hours before baking. Leftovers keep 3-4 days in the fridge. The breadcrumb topping stays crisp if you cover with foil while storing.

Step-by-Step Instructions for Kraft Mac and Cheese Tuna Casserole

Here’s my proven method that turns simple ingredients into a nostalgic comfort classic.

Step 1: Prepare the Base and Cook Pasta

Preheat your oven to 375°F. Bring a large pot of salted water to a boil and cook the Kraft Macaroni and Cheese Dinner according to package directions, but reduce the cooking time by 1 minute—it will finish in the oven. Drain and return it to the pot.

While the pasta cooks, drain the 2 cans Canned Tuna in Water thoroughly in a colander, pressing gently with a spoon to remove excess moisture. This prevents the casserole from becoming watery. Set the tuna aside in a bowl.

Step 2: Build the Creamy Cheese and Tuna Mixture

In the pot with the cooked pasta, add the 0.75 cup Milk, 4 tbsp Unsalted Butter, and the cheese packet from the Kraft Macaroni and Cheese Dinner. Stir over low heat until the butter melts and the sauce is smooth. Remove from heat.

Add the drained tuna, 1 cup Frozen Peas, 1/2 diced Yellow Onion, 2 minced Garlic Cloves, 1 tbsp Dijon Mustard, 1 tsp Worcestershire Sauce, 0.5 tsp Salt, and 0.25 tsp Black Pepper. Stir gently until everything is evenly distributed. The peas will thaw from the residual heat.

Step 3: Thicken and Enhance the Sauce

In a small bowl, whisk together the 2 tbsp All-Purpose Flour with 2 tablespoons of the milk from the casserole mixture to create a slurry. Pour this back into the pot and stir well. This step ensures the sauce thickens properly without clumping.

Fold in the 1 cup Shredded Cheddar Cheese until fully melted and incorporated. Taste and adjust seasoning if needed—the cheese should be rich and creamy, with a subtle tang from the mustard.

Step 4: Top and Bake to Perfection

Transfer the mixture to a greased 9×13-inch baking dish. In a small bowl, combine the 0.5 cup Breadcrumbs with 0.5 tsp Paprika, then sprinkle evenly over the top. The paprika adds a touch of color and a subtle smoky note.

Bake for 20-25 minutes until the casserole is bubbling at the edges and the breadcrumb topping is golden brown. Let it rest for 5 minutes before serving to allow the sauce to set slightly—this makes it easier to portion and ensures every bite is creamy and flavorful.

Wine and Beer Pairings for This Recipe

Crisp White Wines

For this creamy dish, a Sauvignon Blanc with its bright acidity cuts through the richness beautifully. I love a New Zealand style like Oyster Bay—its citrus and herbal notes balance the cheesy tuna perfectly. Serve slightly chilled.

Light Beer Pairings

A crisp American lager like Bud Light or Coors Banquet offers a refreshing contrast without competing flavors. The carbonation cleanses your palate between bites. For more depth, try a pilsner with its slight hop bitterness. 🍺

Rich White Options

If you prefer a fuller-bodied white, Chardonnay works if it’s unoaked or lightly oaked. The buttery notes complement the cheese sauce while the acidity keeps the dish from feeling too heavy. I recommend Kendall-Jackson Vintner’s Reserve.

Rosé for Balance

A dry rosé like Whispering Angel provides the perfect middle ground with its crisp acidity and subtle red fruit notes. It’s versatile enough to handle both the cheese and tuna components without overwhelming either. 🍷

Non-Alcoholic Choices

For those skipping alcohol, a sparkling lemonade with its effervescence and citrus works wonderfully. I make mine with 1 part lemon juice to 3 parts club soda and a touch of honey. The bubbles mimic beer’s palate-cleansing effect.
