CREAMY TOMATO SAUCE FOR RAVIOLI RECIPES

Steps:

• Bring a large pot of lightly salted water to a boil. Add pasta and cook for 8 to 10 minutes or until al dente; drain.
• Heat olive oil in a large skillet over medium heat. Saute onion until tender and translucent. Stir in garlic and butter, and saute until garlic is soft and fragrant, about 1 minute. Dissolve flour in milk, then stir in. Season with salt and pepper, and simmer 4 minutes, stirring constantly. Add cheese, and stir until melted. Stir in pesto. Add shrimp, mushrooms and tomatoes. Cook 4 minutes, or until heated through. Toss with pasta until evenly coated.

Steps:

• Add the pancetta to a heavy large skillet over medium heat. Add olive oil and saute until golden brown, about 8 minutes. Add the onion and saute until tender, about 5 minutes. Season with salt. Add the garlic and red pepper flakes. Saute until fragrant, about 30 seconds. Stir in the tomato puree. Simmer uncovered over medium-low heat until the sauce thickens slightly and the flavors blend, about 15 minutes. Season the sauce with salt, to taste.
• Meanwhile, boil the linguine in a large pot of boiling salted water until tender but still firm to the bite, stirring occasionally, about 8 minutes. Drain, reserving 1 cup of the cooking liquid.
• Toss the linguine with the sauce in the skillet, adding some of the reserved cooking liquid until the pasta is moist but being careful not to dilute the sauce. Toss with the cheese. Season with salt, to taste.
