High Protein Tuna Pasta Bake Under 500 Calories

You open the fridge on a Tuesday night and need dinner that works for your goals. A creamy, cheesy pasta bake that actually fits a calorie deficit sounds too good to be true. But this high protein tuna pasta bake under 500 calories delivers 40 grams of protein per serving without the heavy cream or excessive cheese. It uses cottage cheese blended into a silky sauce, whole wheat pasta for fiber, and canned tuna for lean protein. This version keeps the comfort food feel while supporting weight loss or muscle maintenance.

This recipe was built for real weeknights. You can have it on the table in 40 minutes with minimal cleanup. It reheats well for lunch the next day, which makes it practical for meal prep. The ingredients are affordable and easy to find at any grocery store.

If you have tracked calories before, you know pasta dishes often push past 600 or 700 calories per serving. This one stays under 500 while still tasting satisfying. The secret is replacing heavy cream with blended cottage cheese and using a modest amount of sharp cheddar for flavor.

Is High Protein Tuna Pasta Bake Under 500 Calories Good for Weight Loss?

Yes, this recipe works well for weight loss because it provides high protein and moderate fiber in a controlled calorie package. Protein keeps you full longer than carbohydrates or fat alone, which can reduce snacking later in the evening. Each serving delivers roughly 40 grams of protein, which is nearly two-thirds of the daily recommendation for many women.

One honest caveat: this is still a pasta dish. It contains around 45 grams of carbohydrates per serving, so it may not suit very low-carb diets. But for most people following a balanced calorie deficit, the fiber from whole wheat pasta helps slow digestion and stabilize blood sugar.

I always add an extra pinch of black pepper and a dash of smoked paprika to the sauce. It makes a noticeable difference without adding any calories.

• 1 tbsp olive oil
• 2 cloves garlic, minced
• 1 small onion, diced

How to Make High Protein Tuna Pasta Bake Under 500 Calories Step by Step

1. Preheat the oven to 375°F. Lightly grease a 9×13 inch baking dish.
2. Cook the pasta according to package directions until al dente. Drain and set aside. Do not overcook, as the pasta will continue cooking in the oven.
3. Heat olive oil in a large skillet over medium heat. Add the diced onion and cook for 3 minutes until softened.
4. Add minced garlic and cook for 30 seconds until fragrant.
5. Blend the cottage cheese and broth together in a blender or food processor until smooth. This creates the creamy sauce base.
6. Pour the blended cottage cheese mixture into the skillet with the onions. Stir in the Greek yogurt, salt, pepper, and smoked paprika.
7. Fold in the drained tuna, frozen peas, and cooked pasta. Stir until everything is evenly coated.
8. Transfer the mixture to the prepared baking dish. Sprinkle the shredded cheddar cheese evenly on top.
9. Bake for 20 minutes until the cheese is melted and bubbly. Let it rest for 5 minutes before serving.
