Ingredients

  • 12 oz farfalle pasta
  • 2 large yellow onions, thinly sliced
  • 2 tablespoons olive oil (divided)
  • 2 cups cremini or button mushrooms, sliced
  • 3 cups fresh spinach leaves
  • 3 cloves garlic, minced
  • 1/2 cup grated Parmesan cheese (optional)
  • 1/2 teaspoon salt (or to taste)
  • 1/4 teaspoon black pepper
  • 1/2 teaspoon dried thyme (optional)
  • Fresh parsley for garnish (optional)

Instructions

  1. Step 1: Heat 1 tablespoon of olive oil in a large skillet over medium-low heat. Add the sliced onions and cook, stirring occasionally, for 20-25 minutes until golden and caramelized. Reduce heat if they begin to brown too quickly. Remove onions from the skillet and set aside.
  2. Step 2: Bring a large pot of salted water to a boil. Add the farfalle pasta and cook according to package instructions until al dente. Reserve 1/2 cup of pasta water, then drain the pasta.
  3. Step 3: In the same skillet, heat the remaining tablespoon of olive oil over medium heat. Add the minced garlic and cook for 1 minute until fragrant. Stir in the sliced mushrooms and sauté for 5-6 minutes until browned.
  4. Step 4: Add the fresh spinach to the skillet and cook for 2-3 minutes until wilted.
  5. Step 5: Return the caramelized onions to the skillet, add the cooked pasta, and toss to combine. Add reserved pasta water as needed to create a cohesive sauce.
  6. Step 6: Season the dish with salt, black pepper, and dried thyme if using. Serve topped with grated Parmesan cheese and fresh parsley if desired.

Tips & Variations

  • For extra richness, stir in a tablespoon of butter when combining the pasta with the vegetables.
  • Substitute kale or Swiss chard for spinach for a heartier green.
  • Add toasted pine nuts or walnuts for a crunchy texture.
  • Use vegan Parmesan or nutritional yeast to keep the dish dairy-free.

Storage

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over low heat, adding a splash of water to loosen the sauce if it has thickened.

For the Pasta Dish

  • 12 oz farfalle pasta
  • 2 large yellow onions, thinly sliced
  • 2 tablespoons olive oil (divided)
  • 2 cups cremini or button mushrooms, sliced
  • 3 cups fresh spinach leaves
  • 3 cloves garlic, minced
  • 1/2 cup grated Parmesan cheese (optional)
  • 1/2 teaspoon salt (or to taste)
  • 1/4 teaspoon black pepper
  • 1/2 teaspoon dried thyme (optional)
  • Fresh parsley for garnish (optional)

Instructions

  1. Caramelize the Onions: Heat 1 tablespoon of olive oil in a large skillet over medium-low heat. Add the thinly sliced onions and cook, stirring occasionally, for 20-25 minutes until they become golden and caramelized. If the onions start browning too quickly, reduce the heat. Once caramelized, remove the onions from the skillet and set them aside.
  2. Cook the Pasta: Bring a large pot of salted water to a boil. Add the farfalle pasta and cook according to the package instructions until al dente. Before draining, reserve 1/2 cup of the pasta cooking water.
  3. Sauté the Mushrooms and Spinach: In the same skillet used for the onions, heat the remaining 1 tablespoon of olive oil over medium heat. Add the minced garlic and cook for about 1 minute until fragrant. Then add the sliced mushrooms and sauté for 5-6 minutes until they turn golden brown. Stir in the fresh spinach and cook for an additional 2-3 minutes until wilted.
  4. Combine and Serve: Return the caramelized onions to the skillet and add the cooked farfalle pasta. Toss everything together, adding some of the reserved pasta water as needed to create a cohesive sauce. Season with salt, black pepper, and dried thyme if using. Serve the pasta with a sprinkle of grated Parmesan cheese and garnish with fresh parsley if desired.

Notes

  • You can substitute cremini mushrooms with button or portobello mushrooms for different flavors.
  • For a vegan version, omit the Parmesan cheese or use a plant-based alternative.
  • Reserve pasta water is essential to help create a silky sauce that clings to the pasta.
  • Caramelizing onions slowly over low heat is key to developing rich sweetness and flavor.
  • Fresh parsley can be omitted or replaced with basil or chives depending on preference.
