Tuna Casserole Recipe Ingredients
For the Casserole
• Canned Tuna – The main protein source; choose chunk light tuna packed in water for a leaner option.
• Greek Yogurt – Replaces heavy cream/mayo to create a creamy, tangy sauce; use plain, unsweetened, full-fat for the best taste.
• Pasta (Whole Wheat/Chickpea) – Adds structure; ensure you cook al dente to avoid mushiness, or opt for gluten-free pasta if needed.
• Frozen Peas – Little bursts of sweetness and color; no need to thaw them before adding to the mix.
• Cheese (Sharp Cheddar & Mozzarella) – Brings creaminess and flavor; substitute with dairy-free cheese for a unique twist.
For the Aromatics
• Onion – Sauté until translucent to build a fragrant base; to enhance sweetness, use a yellow onion.
• Garlic – Adds depth and deliciousness; fresh minced garlic is best for maximizing flavor impact.
For Flavor
• Dijon Mustard – Infuses tang and complexity into the sauce; it’s essential for elevating the overall flavor.
For Topping (Optional)
• Breadcrumbs – Adds a delightful crunch; using panko breadcrumbs creates a lighter, crispier topping.
This tuna casserole recipe is perfect for anyone looking for a nourishing and comforting meal that transcends ordinary weeknight dinners!
Step‑by‑Step Instructions for High-Protein Tuna Casserole with Greek Yogurt Sauce
Step 1: Preheat the Oven
Start by preheating your oven to 375°F (190°C). This ensures that your casserole will bake evenly and arrive at the perfect temperature for serving. While the oven warms up, gather your baking dish and have it ready to hold the creamy tuna casserole mix.
Step 2: Cook the Pasta
In a large pot, bring salted water to a boil and cook your pasta (whole wheat or chickpea) until al dente, about 8-10 minutes. Be sure to check for that perfect bite! Reserve ½ cup of the pasta water for later use, then drain the rest and set the pasta aside to cool slightly, giving it time to firm up before it joins the rest of the ingredients.
Step 3: Sauté Aromatics
In a skillet, heat a tablespoon of olive oil over medium heat. Add chopped onions and sauté for approximately 4 minutes, or until they become translucent and fragrant. Next, stir in minced garlic and cook for an additional minute, releasing a wonderful aroma that forms the savory base of your tuna casserole.
Step 4: Prepare the Sauce
In a large mixing bowl, combine the sautéed onion and garlic with Greek yogurt, Dijon mustard, and half of the shredded cheese. Mix everything until you have a smooth and creamy sauce. If the mixture feels too thick, gradually add in the reserved pasta water until you reach your desired consistency for the casserole.
Step 5: Combine Ingredients
Gently fold in your drained tuna, the cooked pasta, and frozen peas into the sauce mixture until well incorporated. The high-protein tuna casserole mix should be vibrant and well-coated. Once combined, transfer this hearty filling to your greased baking dish, spreading it out evenly to ensure even cooking.
Step 6: Add Toppings
Sprinkle the remaining cheese over the top of the casserole mixture for that irresistible cheesy finish. Optional: For an extra crunchy texture, mix breadcrumbs with a splash of olive oil and sprinkle this mixture over the cheese layer, giving your casserole a delicious golden crust as it bakes.
Step 7: Bake the Casserole
Place the baking dish in the preheated oven and bake uncovered for about 20-25 minutes. Keep an eye on it—you’re looking for bubbly cheese and a golden, slightly crispy top. This homemade tuna casserole will be the ultimate comfort dish, filled with creamy goodness.
Step 8: Rest Before Serving
Once baked to perfection, remove the casserole from the oven and let it rest for about 5 minutes. This brief cooling period allows the flavors to settle. Serve your delightful high-protein tuna casserole warm, perhaps with a squeeze of lemon for an added touch of brightness!
Make Ahead Options
These High-Protein Tuna Casseroles are perfect for meal prep enthusiasts navigating busy weeknights! You can assemble the entire casserole up to 24 hours in advance before baking. Simply follow the recipe up until the baking step, then cover the dish tightly with foil and refrigerate. This helps maintain the casserole’s freshness and flavor. When you’re ready to enjoy it, just preheat your oven and bake for about 30-35 minutes (adding an extra 5-10 minutes if baking straight from the fridge), until the cheese is bubbly and golden. By prepping in advance, you save valuable time while still providing your family with a nutritious and delicious meal.

High-Protein Tuna Casserole with Greek Yogurt Sauce Recipe FAQs
What type of canned tuna is best for this recipe?
Absolutely! For the best flavor and texture, I recommend using chunk light tuna packed in water. It’s leaner and has a milder taste. Be sure to drain it well to prevent sogginess in your casserole.
How should I store leftover tuna casserole?
Very good question! You can store leftovers in an airtight container in the fridge for up to 3 days. When reheating, a splash of broth or water can help maintain moisture and flavor—just pop it back in the oven or microwave until warmed through!
Can I freeze the tuna casserole, and if so, how?
Absolutely! To freeze, allow your baked casserole to cool completely, then transfer it into a tightly sealed freezer-safe container. It’s best preserved for up to 3 months. When you’re ready to enjoy it, thaw it overnight in the fridge, then reheat at 350°F (175°C) until warmed thoroughly—about 15-20 minutes.

What can I do if my casserole comes out too dry?
No problem! If your casserole is dry, next time, ensure that you don’t overcook the pasta. You can also add a little reserved pasta water to the sauce to keep it creamy. If it already came out dry, consider serving it with a side of broth or a saucy relishing that can be spooned over for added moisture.
