Instructions

  1. Step 1: Bring a large pot of salted water to a boil. Add 12 oz spaghetti and cook for 8-10 minutes until al dente; reserve 1/2 cup pasta water before draining.
  2. Step 2: Heat 2 tbsp olive oil in a large skillet over medium heat. Add 4 minced garlic cloves and 1/4 tsp red pepper flakes, sautéing for 1 minute until fragrant.
  3. Step 3: Stir in 1 can (14 oz) diced tomatoes and 1 cup chicken broth; simmer for 5 minutes until slightly thickened.
  4. Step 4: Add drained spaghetti and 4 oz fresh spinach to the skillet, stirring until spinach wilts and sauce coats pasta. Add reserved pasta water 1 tbsp at a time if needed to reach desired consistency.
