Ingredients

2 tbsp. extra-virgin olive oil, plus more for baking dish

1 onion, chopped

2 c. thinly sliced mushrooms, divided

3 garlic cloves, minced

2 tbsp. tomato paste

1 (28-oz.) can crushed tomatoes

2 sprigs fresh basil

Kosher salt

Freshly ground black pepper

2 (9-oz.) packages refrigerated cheese tortellini

3/4 c. pepperoni, divided

2 tbsp. sliced black olives

1/4 c. freshly sliced basil, for garnish

Preparation

Step 1Preheat oven to 350°. In a large skillet over medium-high heat, heat oil. Add onion and 1 ¾ cup mushrooms and cook, stirring, until soft, about 6 minutes. Add garlic and cook until fragrant, 1 minute. Add tomato paste and cook stirring, until darkened slightly, about 1 minute. Add crushed tomatoes, 1 cup water, and basil and season with salt and pepper. Bring mixture to a simmer and cook until slightly reduced, about 10 minutes. Remove basil sprigs. Step 2Remove skillet from heat and add tortellini and ½ cup pepperoni to skillet. Stir until coated. Top with mozzarella, remaining ¼ cup pepperoni, remaining ¼ cup mushrooms, and olives, then cover skillet with foil. Step 3Bake until cheese has melted and pasta is cooked through, 25 minutes. Broil until golden, about 2 minutes more. Garnish with basil before serving.
