Instructions

  1. Step 1: Heat 2 tbsp olive oil in a large skillet over medium heat until shimmering, about 1 minute.
  2. Step 2: Add 4 minced garlic cloves and 1/2 tsp red pepper flakes, cooking for 30 seconds until fragrant but not browned.
  3. Step 3: Pour in 1 cup canned crushed tomatoes, then season with 1/2 tsp salt and 1/4 tsp black pepper. Simmer the sauce for 8 minutes until it thickens slightly.
  4. Step 4: Meanwhile, place 4 medium spiralized zucchini noodles in a colander and sprinkle with a pinch of salt to draw out moisture; let sit for 5 minutes, then gently squeeze dry.
  5. Step 5: Add the zucchini noodles to the skillet with the tomato sauce and toss for 2-3 minutes over medium heat until the noodles are warmed but still slightly firm.
  6. Step 6: Remove from heat and stir in 1/4 cup chopped fresh basil.
  7. Step 7: Serve immediately, optionally topped with 1/4 cup grated Parmesan cheese.
