Ingredients You’ll Need

Here’s everything that makes this dish so flavorful and satisfying:

Pasta

• 12 ounces penne, rigatoni, or ziti
  Short pasta shapes work best because they hold onto the creamy pesto sauce.

Vegetables

• 1 zucchini, chopped
• 1 red bell pepper, diced
• 8 ounces mushrooms, sliced
• 1 cup cherry tomatoes, halved
• 2 cups fresh spinach

These vegetables add texture, sweetness, and depth while keeping the dish hearty and colorful.

Sauce & Flavor

• ¾ cup sundried tomato pesto
• 1 cup heavy cream (or half-and-half)
• 3 cloves garlic, minced
• 1 teaspoon Italian seasoning
• Salt and black pepper to taste
• 1–2 tablespoons olive oil

Cheese

• 1 ½ cups shredded mozzarella
• ½ cup grated parmesan

Freshly shredded cheese melts more smoothly and gives the best texture.

How to Make Sundried Tomato Pesto Pasta Bake

1. Cook the Pasta

Bring a large pot of salted water to a boil. Cook the pasta until just al dente — slightly undercooked. It will finish cooking in the oven. Drain and set aside.

2. Sauté the Vegetables

In a large skillet, heat olive oil over medium heat. Add garlic and cook until fragrant, about 30 seconds.

Add zucchini, bell pepper, and mushrooms. Cook for 5–7 minutes until tender. Stir in cherry tomatoes and cook for another 2 minutes. Season with salt, pepper, and Italian seasoning.

Add spinach last and cook just until wilted.

3. Make the Creamy Pesto Sauce

Lower the heat and stir in the sundried tomato pesto and cream. Let the mixture gently simmer for 2–3 minutes until slightly thickened.

Taste and adjust seasoning as needed. If the sauce feels too thick, add a splash of reserved pasta water.

4. Combine Everything

Add the cooked pasta to the skillet and toss until evenly coated with the sauce and vegetables.

Transfer everything to a greased 9×13-inch baking dish. Sprinkle mozzarella and parmesan evenly over the top.

5. Bake Until Golden

Bake at 375°F (190°C) for 20–25 minutes, or until bubbly and golden. For a crispier top, broil for 2–3 minutes at the end.

Let the pasta bake rest for 5–10 minutes before serving. This helps it set and makes slicing easier.

The Best Vegetables for Pasta Bake

One of the best things about this sundried tomato pesto pasta bake is how versatile it is. You can easily swap or add vegetables based on seasonality or preference.

Great additions include:

• Broccoli florets
• Roasted eggplant
• Kale
• Artichoke hearts
• Asparagus
• Caramelized onions
• Extra sundried tomatoes

The key is balancing texture. Softer vegetables like spinach should be added at the end, while firmer vegetables like broccoli benefit from pre-cooking or roasting.

Tips for the Creamiest Pasta Bake

If you want restaurant-quality results, keep these tips in mind:

• Slightly undercook the pasta to prevent mushiness
• Use freshly grated cheese for better melting
• Taste your pesto before adding salt, some brands are saltier than others
• Don’t skip the resting time after baking
• Add a splash of cream when reheating leftovers to restore creaminess

These small details make a big difference in texture and flavor.

How to Store, Freeze, and Reheat

Reheating

Reheat in the oven at 350°F until warmed through. Add a splash of milk or cream to keep it from drying out. Cover with foil to retain moisture.

This makes it ideal for meal prep or doubling the recipe for later.
