• 1 tablespoon olive oil or butter, or as needed
• 1/2 onion, finely chopped
• 3 cloves garlic, minced
• 4 ounces pancetta, diced
• 6 ounces frozen peas
• 8 ounces cooked farfalle pasta
• 2 cups béchamel sauce (or other jarred creamy sauce)
• 2 tablespoons butter (optional)
• Parmesan cheese, freshly grated (optional)

Instructions:

1. Preheat the oven to 350 degrees F (175 degrees C).
2. Heat olive oil or butter in a large skillet over medium heat. Add onion and cook until translucent, then add garlic and cook until fragrant. Stir in pancetta and frozen peas. Cook until warmed through and pancetta has crisped up a bit.
3. Combine cooked pasta, béchamel, and pancetta mixture in a casserole dish. Dot with butter and top with grated Parmesan cheese.
4. Bake, uncovered, until the sauce is bubbly and the top is lightly browned, about 20 minutes.
