Step-by-Step Instructions
Step 1: Prepare Your Pasta
Bring a large pot of salted water to a boil. Add pasta and cook according to package instructions until al dente. Tip: Reserve 1/2 cup of pasta water before draining – this starchy liquid is the secret to silky sauce consistency.
Step 2: Create the Flavor Base
In a large skillet over medium heat, warm the olive oil. Add minced garlic and diced onion, sautéing for 2-3 minutes until fragrant and translucent. The aromatic compounds in garlic become most bioavailable when cooked this way, enhancing both flavor and health benefits.
Step 3: Build the Sauce
Add crushed tomatoes to the garlic-onion mixture. Stir in dried basil and red pepper flakes. Bring to a gentle simmer and cook for 5 minutes, allowing the flavors to meld. Season with salt and pepper to taste.
Step 4: Add Creaminess
Lower the heat and stir in the heavy cream and grated Parmesan. The optimal temperature for cream integration is just below simmering (about 180°F/82°C) to prevent curdling. Stir continuously until fully incorporated into a smooth, velvety creamy garlic tomato sauce.
Step 5: Combine and Serve
Add the drained pasta to the sauce, tossing thoroughly to coat. If needed, add a splash of reserved pasta water to reach desired consistency. Garnish with fresh parsley and additional Parmesan before serving.
