Instructions

1. Step 1: Preheat oven to 400°F. Toss 2 cups halved cherry tomatoes with 2 tbsp olive oil and 1/2 tsp salt on a baking sheet. Roast for 15 minutes until tomatoes are soft and caramelized.
2. Step 2: In a large pot, heat 2 tbsp olive oil over medium heat. Add 5 thinly sliced garlic cloves and 1/4 tsp red pepper flakes, sautéing for 1-2 minutes until fragrant but not browned.
3. Step 3: Add 12 oz dry spaghetti to the pot along with 4 cups vegetable broth, 1/2 tsp salt, and 1/2 tsp black pepper. Bring to a boil, then reduce heat to medium-low and simmer uncovered, stirring occasionally, for 10-12 minutes until pasta is al dente and liquid has mostly absorbed.
4. Step 4: Stir in the roasted tomatoes and 1/4 cup chopped fresh basil, tossing gently to combine. Remove from heat and, if desired, sprinkle with 1/2 cup grated parmesan cheese before serving.
