Description

This Creamy Vegan Caramelized Onion Pasta combines sweet, jammy onions with a velvety oat-based cream sauce, vegan Parmesan, and a touch of chili oil for gentle heat. Cozy yet elegant, it’s a plant-based comfort dish that’s both simple and flavorful.


Ingredients

  • 8 oz pasta of choice
  • 34 large onions, thinly sliced
  • 3 tbsp olive oil
  • 1 tbsp vegan butter or regular butter (optional)
  • 1 tsp sugar (optional)
  • 4 cloves garlic, minced
  • ¾ cup oat cream (or heavy cream)
  • 1 cup vegan Parmesan (or regular Parmesan)
  • 2 tbsp chili oil
  • Seasonings: smoked paprika, onion powder, garlic powder, dried oregano, sweet paprika, salt, black pepper
  • Fresh parsley, chopped (for garnish)

Instructions

  1. Caramelize the onions: Heat olive oil and butter in a skillet over medium heat. Add onions, season with salt and pepper, and cook 5 minutes until softened. Stir in garlic and sugar. Add a splash of water and cook low and slow for 25–30 minutes, stirring occasionally, until golden and jammy. Deglaze with water as needed.
  2. Cook the pasta: While onions cook, boil pasta in salted water until al dente. Reserve 1 cup pasta water, then drain.
  3. Make the sauce: To the onions, add chili oil, spices, oat cream, and vegan Parmesan. Simmer 5–7 minutes until thickened. Loosen with pasta water if needed.
  4. Combine: Toss the pasta with the sauce until well coated. Adjust seasoning to taste.
  5. Serve: Garnish with fresh parsley and extra Parmesan before serving hot.

Notes

  • Make it gluten-free by swapping the pasta for a GF variety.
  • Use coconut or soy cream if oat cream isn’t available.
  • For less spice, omit the chili oil.
  • Boost protein with sautéed mushrooms or crispy tofu.
  • Add spinach or kale at the end for extra greens.
