Description
This Creamy Vegetable Pasta Casserole is a cozy, colorful baked dinner loaded with tender pasta, broccoli, bell peppers, spinach, and cherry tomatoes in a creamy Greek yogurt sauce. A golden layer of mozzarella and Parmesan melts beautifully over the top, creating the perfect combination of creamy, cheesy, and comforting flavors.
It is an easy family-friendly meal that works beautifully for meal prep and leftovers. Greek yogurt and cheese make it more highprotein-friendly, while the generous vegetables add color, texture, and fiber. Traditional pasta keeps this recipe from being low-carb, but chickpea or lentil pasta can make it more protein-focused.
Can This Creamy Vegetable Pasta Casserole Support Weight Loss Goals?
Yes, it can fit into a balanced eating pattern when portion size and the rest of the meal are considered. Pasta provides carbohydrates, while broccoli, spinach, bell pepper, and tomatoes add fiber and volume. Using Greek yogurt and a moderate amount of cheese can make the casserole satisfying without depending on an oversized pasta portion.
Does Creamy Vegetable Pasta Casserole Fit a highprotein Lifestyle?
This casserole can fit a highprotein lifestyle thanks to Greek yogurt, mozzarella, and Parmesan. One serving provides approximately 20g of protein, although the dish is not low-carb because regular pasta contributes most of the carbohydrates. For a higher-protein version, use chickpea or lentil pasta and add tofu, beans, or another protein-rich ingredient.

- Overbaking: Remove the casserole once it is bubbling and the cheese is lightly golden to prevent dryness.

For longer storage, freeze cooled portions in freezer-safe containers for up to 2 months. Thaw overnight in the refrigerator for the best texture.
To reheat, microwave individual portions for 2–3 minutes, rotating halfway through, or cover the casserole and warm it in a 350°F/175°C oven for 15–20 minutes. Add a splash of milk if the sauce has thickened.

- 2 cups broccoli florets, cut into small pieces
- 2 cups fresh spinach
- 1 cup cherry tomatoes, halved
Seasonings
- 1 tsp Italian seasoning
- ½ tsp smoked paprika
- ½ tsp black pepper
- ½ tsp salt, or to taste
Creamy Sauce
- 1 cup (240 g) plain Greek yogurt
- 1 cup (240 ml) low-sodium vegetable broth
- ½ cup (120 ml) milk
- 1 tbsp tomato paste
Cheesy Topping
- 1 cup (100 g) shredded mozzarella cheese

- 2 tbsp fresh parsley, chopped, optional
High-protein option: Replace regular pasta with chickpea, lentil, or another higher-protein pasta.
Directions
1. Preheat the Oven
Preheat the oven to 375°F (190°C). Lightly grease a 9 × 13-inch baking dish.
2. Cook the Pasta
Bring a large pot of salted water to a boil over high heat. Cook the pasta until just al dente, about 1–2 minutes less than the package directions. Drain thoroughly.
3. Sauté the Vegetables
Heat olive oil in a large skillet over medium heat. Add onion and bell pepper and cook for about 3 minutes.
Add garlic and broccoli and continue cooking for 2–3 minutes, until the vegetables are bright and slightly tender.
4. Add the Remaining Vegetables
Stir in spinach and cherry tomatoes. Cook until the spinach wilts.
Season with Italian seasoning, smoked paprika, black pepper, and salt.
5. Make the Creamy Sauce
In a mixing bowl, whisk together Greek yogurt, vegetable broth, milk, and tomato paste until smooth.
Do not boil the yogurt mixture, as high heat can cause the sauce to separate.
6. Combine
Add the drained pasta and creamy sauce to the skillet with the vegetables.
Stir gently until everything is evenly coated. The mixture should look slightly saucier than you want the finished casserole because the pasta will absorb some of the liquid during baking.
7. Assemble
Transfer the mixture to the prepared baking dish and spread it into an even layer.
Sprinkle the mozzarella and Parmesan evenly over the top.
8. Bake
Bake uncovered at 375°F (190°C) for 20–25 minutes, until the sauce is bubbling around the edges and the cheese is melted and lightly golden.
9. Rest
Remove from the oven and let the casserole rest for 5–10 minutes. This allows the sauce to settle and makes serving easier.
10. Garnish and Serve
Sprinkle with fresh parsley and serve warm.
High-Protein Cooking Tips
- Use chickpea or lentil pasta to substantially increase the protein content.
- Choose plain Greek yogurt rather than regular yogurt for a thicker, protein-rich sauce.
- Add cooked tofu, white beans, lentils, or plant-based protein pieces for a heartier meal.
- Keep the vegetable-to-pasta ratio generous so each serving contains vegetables alongside protein and carbohydrates.
