How to Make High-Protein Tuna Casserole
-
Boil Water: Bring a large pot of salted water to a boil. Once boiling, add the whole wheat or chickpea pasta. Cook until al dente, about 8-10 minutes, then drain it, reserving ½ cup of pasta water.
-
Sauté Aromatics: Heat 1 tablespoon of olive oil in a skillet over medium heat. Add the finely chopped onion and cook for about 4 minutes until it’s soft and translucent. Then, add the minced garlic and let it cook for another minute until fragrant.
-
Mix Sauce: In a large mixing bowl, combine the sautéed onion and garlic with Greek yogurt, Dijon mustard, and half of the shredded cheese. Stir everything together until it’s creamy, adding reserved pasta water to adjust consistency if needed.
-
Combine Ingredients: Gently fold the drained tuna, cooked pasta, and frozen peas into the yogurt mixture. Stir carefully to combine, being mindful not to break up the tuna too much.
-
Prepare for Baking: Transfer the mixture into a greased 8×8 inch (20×20 cm) baking dish. Sprinkle the remaining cheese evenly over the top. If you’re using breadcrumbs, toss them in a little olive oil and scatter them over the cheese for extra crunch.
-
Bake: Preheat your oven to 375°F (190°C). Bake uncovered for 20-25 minutes, until the cheese is bubbly and golden brown. Allow it to rest for 5 minutes before serving to let all the flavors meld.
Optional: Garnish with fresh herbs like dill or parsley for a burst of flavor.

Tips for the Best High-Protein Tuna Casserole
• Cook Pasta Perfectly: Always aim for al dente pasta, as it will continue to cook in the oven and prevent mushiness in your high-protein tuna casserole.
• Sauté Aromatics Gently: Ensure your onions and garlic are sautéed on medium heat until soft. This step builds a rich base and enhances flavors without burning them.
• Adjust Creaminess: If your Greek yogurt mixture feels too thick, don’t hesitate to add the reserved pasta water a little at a time. It helps create a smoother sauce without adding extra calories.
• Don’t Overmix: When folding in the tuna, pasta, and peas, be gentle to preserve the texture of the tuna. Overmixing can result in a mushy casserole.
• Customize Your Dish: Feel free to add your favorite vegetables, like bell peppers or spinach, to make this dish even more nutritious and delicious!

High-Protein Tuna Casserole Recipe FAQs
How do I pick the best tuna for my casserole?
Absolutely! When choosing tuna, look for chunk light tuna packed in water for a mild flavor and lower mercury content. Check the expiration date and opt for brands that are sustainably sourced, if possible. For a bit of variety, you might also try albacore tuna, which has a firmer texture.
What’s the best way to store leftover tuna casserole?
Very! Store your leftovers in an airtight container in the fridge for up to 3 days. Make sure to allow the casserole to cool to room temperature before sealing it to maintain freshness. If you want to enjoy it later, simply pop it in the microwave for a quick meal!
