A flexible, quick, and satisfying pasta recipe using leftover ingredients from your fridge, perfect for busy weeknights and minimizing food waste.

Ingredients

Scale
  • 8 ounces pasta (any type: spaghetti, penne, fusilli, or leftover cooked pasta)
  • 2 tablespoons extra virgin olive oil
  • 3 garlic cloves, minced or thinly sliced
  • 1 small onion or 2 shallots, finely chopped
  • 2 cups mixed vegetables (bell peppers, zucchini, spinach, cherry tomatoes, mushrooms, frozen peas or corn)
  • Optional protein: leftover cooked chicken, cooked sausage, canned beans, or a fried egg
  • 1/4 cup grated Parmesan or crumbled feta cheese
  • Fresh herbs (parsley, basil, oregano) or dried Italian seasoning
  • Salt and pepper to taste
  • Pinch of red pepper flakes (optional)
  • 1 cup reserved pasta cooking water

Instructions

  1. Bring a large pot of salted water to a boil. Add 8 ounces of pasta and cook according to package instructions until al dente (about 8-10 minutes). Reserve 1 cup of pasta cooking water before draining.
  2. While pasta cooks, mince garlic cloves and finely chop onion or shallots. Chop about 2 cups of vegetables and prepare any protein by shredding or dicing.
  3. Heat 2 tablespoons olive oil in a large skillet over medium heat. Add garlic and onion and cook until fragrant and translucent, about 3-4 minutes, avoiding burning the garlic.
  4. Add vegetables and cook until tender, about 5-7 minutes, stirring occasionally. Add protein now if using and warm through.
  5. Add drained pasta to the skillet, pour in about 1/2 cup of reserved pasta water, and toss to combine over medium heat. Add more pasta water if mixture seems dry.
  6. Season with salt, pepper, and red pepper flakes if desired. Stir in grated Parmesan or crumble feta cheese. Add chopped fresh herbs at the end.
  7. Serve immediately, optionally topped with extra cheese or a drizzle of olive oil.

Notes

Reserve pasta cooking water to create a silky sauce. Avoid burning garlic by cooking on medium heat. Toss pasta immediately after draining to absorb flavors. Use whatever vegetables and proteins you have on hand. For gluten-free, use gluten-free pasta or zucchini noodles. For dairy-free, substitute cheese with nutritional yeast and use vegan butter or olive oil.
