Ingredients
Scale
Pasta
- 12 oz spaghetti or fettuccine
Caramelized Onions
- 3 large yellow onions, thinly sliced
- 3 tbsp unsalted butter
- 1 tbsp olive oil
- 1 tsp salt
- ½ tsp black pepper
- ¼ tsp red pepper flakes (optional)
- 2 cloves garlic, minced
- 1 tsp fresh thyme leaves or ½ tsp dried thyme
Mixer & Garnish
- ½ cup grated Parmesan cheese
- ½ cup reserved pasta water
- Extra Parmesan and chopped parsley for garnish
Instructions
- Cook the Pasta: Bring a large pot of salted water to a boil. Add the spaghetti or fettuccine and cook according to the package directions until al dente. Reserve ½ cup of the pasta cooking water, then drain the pasta and set aside.
- Caramelize the Onions: In a large skillet over medium-low heat, melt the butter with olive oil. Add the thinly sliced onions and cook slowly, stirring frequently, for 25 to 30 minutes. Cook until onions become deeply golden and caramelized. If the onions start to dry out or stick, add a splash of water to deglaze the pan.
- Add Aromatics and Seasoning: Stir in the minced garlic, thyme leaves, salt, black pepper, and red pepper flakes if using. Cook for an additional 2 to 3 minutes until the garlic is fragrant and softened.
- Toss Pasta with Onions: Add the drained pasta directly into the skillet with the caramelized onions. Pour in the reserved pasta water and sprinkle in the grated Parmesan cheese. Toss everything together thoroughly to coat the pasta in a glossy, flavorful sauce.
- Serve: Plate the pasta warm and garnish with extra Parmesan cheese and chopped parsley for a fresh, vibrant finish.
Notes
- For added richness, stir in a splash of cream or a spoonful of mascarpone while tossing the pasta.
- This dish pairs wonderfully with a side salad or crusty bread for a complete meal.
- Make the dish heartier by adding sautéed mushrooms or crispy pancetta.
