Ingredients
Scale
Main Ingredients
- 2 large onions
- 1 tbsp oil
- 1 tbsp butter
- 1/4 tsp salt
- 1 tsp sugar
- 4.5 ounces dry fettuccine pasta
Cashew Cream
- 3/4 cup raw cashews soaked overnight
- 1/2 cup water
- 1 tsp white vinegar
- 1/4 tsp salt
- 1 tbsp nutritional yeast
Instructions
- Slice the onions: Peel and thinly slice the onions to about 1/8 inch (3 mm) thickness for even caramelization.
- Sauté: Heat oil and butter in a large skillet over medium heat. Add onions and a pinch of salt; sauté for 6 minutes until lightly golden.
- Season: Add salt and sugar, continue sautéing for 30 minutes, stirring occasionally until onions are deeply caramelized and golden brown.
- Deglaze: Pour 2 tablespoons of water into skillet to release browned bits, enhancing flavor. Remove skillet from heat and set aside.
- Make the cashew cream: Drain soaked cashews and blend with water, vinegar, salt, and nutritional yeast until smooth for a creamy sauce.
- Cook the pasta: Boil salted water and cook fettuccine according to package directions until al dente. Drain and transfer to skillet with onions.
- Combine: Add cashew cream to pasta and onions, toss to coat. Reheat skillet over medium heat for 5 minutes, stirring frequently. Thin sauce with reserved pasta water if needed.
- Serve: Adjust salt if necessary, garnish with chopped parsley or basil, and black pepper. Serve immediately for best flavor.
Notes
- Do not overcook the pasta; it will finish cooking in the sauce.
- Slice onions evenly at 1/8 inch thickness for optimal caramelization time.
- Watch onions carefully to avoid burning; reduce heat if browning too fast and stir every 3-5 minutes.
- Reserve about 1/3 cup pasta water to thin the sauce as needed; it helps the sauce adhere better.
- Leftovers keep for up to 2 days refrigerated and reheat well.
