Vegan One-Pot French Onion Pasta Recipe
Ingredients:
- 2 tbsp plant-based butter
- 3 large yellow onions, thinly sliced
- 2 cloves garlic, minced
- 1 tsp fresh or dried thyme
- 8 oz pasta (fusilli, campanelle, or your favorite short pasta)
- 3 cups vegetable broth
- 1/4 cup plant-based heavy cream (such as cashew, oat, or soy cooking cream)
- 1/2 cup shredded vegan Gruyère-style cheese
- 1/4 cup grated vegan Parmesan cheese
- Salt and black pepper to taste
- Fresh thyme sprigs for garnish (optional)
Instructions:
- Melt plant-based butter in a large pot or Dutch oven over medium heat. Add the thinly sliced onions and cook, stirring occasionally, until deeply caramelized and soft. This usually takes about 25-30 minutes. Be patient, as this step builds the foundational flavor.
- Stir in the minced garlic and thyme; cook for 1 minute more until fragrant.
- Add the dry pasta and vegetable broth to the pot; bring to a simmer.
- Cook uncovered, stirring occasionally, until the pasta is tender to your liking and the liquid has thickened into a rich, luscious sauce (about 10-15 minutes, depending on your pasta).
- Remove from heat. Stir in the plant-based heavy cream, vegan Gruyère-style cheese, and vegan Parmesan cheese until completely melted and the sauce is velvety smooth.
- Season with salt and black pepper to taste.
- Serve hot, garnished with fresh thyme, and enjoy this delightful Gruyere and Parmesan pasta (vegan style)!

Tips for Success
- Patience with Onions: Don’t rush the caramelization process. Low and slow is the key to deep, rich flavor.
- Choose Your Pasta Wisely: Short pasta shapes like fusilli, campanelle, or penne work best as they absorb the sauce beautifully.
- Adjust Consistency: If your sauce becomes too thick, add a splash more vegetable broth or plant-based milk until it reaches your desired consistency.
- Vegan Cheese Quality: Opt for high-quality vegan cheeses that melt well to achieve the best creamy texture. Many brands now offer excellent vegan Gruyère-style and Parmesan alternatives.
