Step-by-Step Instructions

Step 1: Lightly Grease the Slow Cooker

Lightly coat the inside of a 6-quart slow cooker with nonstick spray or a thin film of olive oil.

Step 2: Add the Base Ingredients

Add the uncooked pasta, vegetable broth, heavy cream, ¾ cup Parmesan cheese, olive oil, garlic, onion, Italian seasoning, basil, salt, black pepper, and red pepper flakes to the slow cooker. Stir to combine.

Step 3: Add the Hearty Vegetables

Scatter the broccoli florets, sliced carrots, and sliced bell peppers over the pasta mixture.

Step 4: Cover and Cook

Cover the slow cooker with the lid and cook on LOW for 2½ to 3 hours, or on HIGH for 1½ to 2 hours, until the pasta is tender and the vegetables are crisp-tender.

Step 5: Add the Delicate Vegetables

Stir in the baby spinach, halved tomatoes, and frozen peas. Cover and cook for another 10 to 15 minutes, until the spinach is wilted and the peas are heated through.

Step 6: Taste and Adjust

Taste the pasta and adjust the seasoning with additional salt and pepper if needed.

Step 7: Serve

Serve hot, topped with the remaining ¼ cup Parmesan cheese and fresh parsley or spinach if desired.

Taste and adjust. Add more salt, pepper, or herbs if needed.
Serve warm. This is best enjoyed hot and fresh.
