1. Step 1: Prepare Your Ingredients

2. First, wash your cherry or grape tomatoes thoroughly. Slice any larger tomatoes in half; smaller ones can stay whole. Mince your garlic cloves finely. Roughly chop your fresh basil. Grate your Parmesan cheese. Measure out your olive oil and vegetable broth or have your pasta water ready.

3. Step 2: Start the Sauce

4. Heat the olive oil in a large skillet or Dutch oven over medium heat. Once the oil shimmers, add the minced garlic and red pepper flakes (if using). Sauté for about 1 minute until fragrant, being careful not to burn the garlic. Burnt garlic tastes bitter, so watch it closely.

5. Step 3: Melt the Tomatoes

6. Next, add all the cherry or grape tomatoes to the skillet. Season generously with salt and black pepper. Stir to coat the tomatoes in the oil and garlic. Cover the skillet and reduce the heat to medium-low. Let the tomatoes cook for about 15-20 minutes, stirring occasionally. During this time, the tomatoes will burst and soften, releasing their juices and creating a beautiful, natural sauce. Gently press down on any stubborn tomatoes with the back of your spoon to help them break down. You want them to truly melt into a sauce, not just soften.

7. Step 4: Cook the Spaghetti

8. While the tomatoes are melting, bring a large pot of salted water to a rolling boil. Add the spaghetti and cook according to package directions until al dente. This usually takes 8-10 minutes. Before draining, reserve about 1 cup of the starchy pasta water. This liquid is gold for creating a silky, emulsified sauce.

9. Step 5: Combine Sauce and Pasta

10. Once the tomatoes have completely broken down into a luscious sauce, remove the skillet from the heat. Add the cooked and drained spaghetti directly into the tomato sauce. Pour in about 1/2 cup of the reserved pasta water or vegetable broth. Stir everything together vigorously. The starch from the pasta water will help create a wonderfully creamy and cohesive sauce that coats every strand. If the sauce seems too thick, add more pasta water, one tablespoon at a time, until you reach your desired consistency.

11. Step 6: Finish and Serve

12. Finally, stir in half of the freshly grated Parmesan cheese and most of the chopped fresh basil. Taste and adjust seasonings as needed. You might need a little more salt or pepper. Serve immediately, garnished with the remaining fresh basil and a generous sprinkle of additional Parmesan cheese. Enjoy this comforting and simple spaghetti recipe!
