Main Ingredients

  • 12 oz dried spaghetti or linguine use your favorite long shape
  • 1.25 lb yellow onions, thinly sliced about 2 large
  • 2.5 tbsp olive oil
  • 1 tbsp vegan butter
  • 2 tsp garlic, minced
  • 1.25 tsp kosher salt divided
  • 0.75 tsp dried thyme
  • 0.25 tsp crushed red pepper flakes optional heat
  • 1.5 tbsp balsamic vinegar
  • 0.75 cup vegetable broth low-sodium preferred
  • 0.5 cup unsweetened oat milk or other plant milk
  • 3 tbsp nutritional yeast
  • 0.5 tsp freshly ground black pepper
  • 1 tbsp fresh lemon juice
  • 0.25 cup fresh parsley, chopped
  • 0.5 cup reserved pasta cooking water add as needed for sauce

Instructions

Preparation Steps

  • Bring a large pot of salted water to a boil for the pasta.
  • Warm olive oil and vegan butter in a wide skillet over medium heat. Add onions and 1/2 teaspoon salt; cook, stirring often, for 10 minutes.
  • Lower heat to medium-low. Continue cooking until onions turn deep golden and jammy, 20–25 minutes, stirring occasionally.
  • Stir in garlic, dried thyme, and red pepper flakes. Cook 1 minute until fragrant.
  • Deglaze with balsamic vinegar, scraping up browned bits. Pour in vegetable broth and oat milk; simmer 3–4 minutes to slightly thicken.
  • Stir in nutritional yeast and black pepper. Taste and add more salt if needed.
  • Cook pasta until al dente. Reserve at least 1/2 cup pasta water, then drain.
  • Toss pasta into the onion sauce over low heat, adding splashes of reserved water until glossy and well-coated.
  • Finish with lemon juice and parsley. Serve immediately.

Notes

Variation: Swap oat milk for 1/3 cup cashew cream for an extra-luxe finish, or fold in sautéed mushrooms or toasted walnuts. For crunch, top with toasted panko. Storage: Refrigerate up to 3 days; reheat gently with a splash of broth or water.
