How to Make Pesto Pasta with Roasted Tomatoes
Step 1: Roast the Tomatoes
Preheat your oven to 400°F (200°C). Toss the tomatoes with olive oil, garlic, salt, and pepper. Spread them on a baking sheet and roast for 15–20 minutes until soft and slightly caramelized.
Step 2: Cook the Pasta
Bring a large pot of salted water to a boil. Cook the pasta according to package instructions until al dente. Reserve about ¼ cup of pasta water before draining.
Step 3: Combine Everything
Return the drained pasta to the pot. Add pesto, a splash of pasta water, and Parmesan cheese. Toss until the pasta is evenly coated and glossy.
Step 4: Add the Tomatoes
Gently fold in the roasted tomatoes, making sure not to crush them too much—they add texture and bursts of flavor.
Step 5: Finish and Serve
Top with fresh basil, extra Parmesan, and a drizzle of olive oil if desired. Serve immediately.
