Ingredients

Scale

Base Ingredients

  • 1 tbsp olive oil (or water)
  • 2 yellow onions, thinly sliced
  • 4 cloves garlic, minced
  • 6 sun-dried tomatoes, chopped
  • 1/2 tsp salt
  • 1 tbsp fresh thyme

Liquids and Sauces

  • 1/2 cup dry white wine
  • 1 cup pasta water (reserved from cooking pasta)
  • 1/2 cup cashew cream (or vegan cream)

Pasta and Greens

  • 12 oz farfalle pasta
  • 1 handful spinach
  • Salt and pepper to taste


Instructions

  1. Heat the oil and soften onions and garlic: In a non-stick pan, heat 1 tablespoon of olive oil or water (oil from the sun-dried tomato jar can be used for extra flavor). Add the thinly sliced onions, minced garlic, and 1/2 teaspoon of salt to help break down the onions. Cook over medium-low heat to gently soften.
  2. Caramelize the onions: Continue cooking the onions and garlic over medium to low heat for approximately 25 minutes, stirring occasionally. This slow cooking brings out the natural sugars in the onions, giving a deep caramelized flavor and golden color.
  3. Cook the pasta: While the onions caramelize, cook 12 ounces of farfalle pasta in a separate pot according to package instructions. Reserve at least 1 1/2 cups of the pasta cooking water before draining the pasta.
  4. Deglaze the pan: Once the onions are caramelized, add 1 tablespoon of fresh thyme, chopped sun-dried tomatoes, and 1/2 cup of dry white wine to the pan. Stir gently to loosen any browned bits from the pan’s bottom and combine the ingredients.
  5. Make the creamy sauce: Add 1 cup of reserved pasta water and 1/2 cup of cashew cream to the onion mixture. Stir until a smooth, creamy sauce forms. Adjust the texture by adding more pasta water if necessary.
  6. Combine pasta and greens: Add the cooked pasta to the pan and mix well to coat the farfalle with the creamy sauce. Toss in a handful of fresh spinach (or basil if preferred) and allow it to wilt slightly from the residual heat.
  7. Season and serve: Taste the pasta and adjust salt and pepper as needed. Serve the pasta immediately to enjoy the fresh, balanced flavors and creamy texture.

Notes

  • This pasta dish is indulgent yet approachable and can be made vegan by using cashew cream instead of dairy-based cream.
  • Using the oil from the sun-dried tomato jar adds an extra depth of tomato flavor to the onions and overall dish.
  • Slow caramelization of onions is key for developing the rich flavor base.
  • Leftover sauce can be stored in the fridge for up to 2 days but is best enjoyed fresh.
  • Farfalles work well for holding the sauce, but any short pasta like penne or rotini can be substituted.
