Preheat oven to 400 degrees Fahrenheit.

Add cherry tomatoes and garlic cloves to a baking dish. Drizzle with olive oil and season with salt and pepper. Place feta cheese in the center.

Bake in the oven for 30 minutes, then increase the oven temperature to 450 degrees and bake for an additional 10 minutes until slightly browned.

Meanwhile, cook pasta in salted water until al dente, then reserve 0.5 cup pasta water and drain.

Remove the baking dish from the oven, mash the feta and tomatoes together, then stir in herbs and red pepper flakes.

Toss the cooked pasta with the feta mixture, adding reserved pasta water to reach desired consistency. Mix in spinach and basil.

Serve warm garnished with additional basil if desired.
