Ingredients
- 4 ounces uncooked pasta
- 1 tablespoon olive oil
- 3 tablespoons butter, divided
- ½ medium onion, chopped
- 8 ounces cremini mushrooms, sliced
- 3 cloves garlic, minced
- ½ teaspoon Dijon mustard
- ¼ cup chicken broth, vegetable broth, or white wine
- ½ teaspoon lemon juice + zest of ½ lemon
- ½ cup freshly grated Parmesan cheese
- 2 tablespoons chopped fresh parsley
- Salt and pepper, to taste
Instructions
- Bring a large pot of salted water to a boil and cook the pasta until al dente, following package instructions.
- While the pasta cooks, heat olive oil and 1 tablespoon of butter in a skillet over medium-high heat. Add the chopped onion and sliced mushrooms. Sauté, stirring occasionally, until the mushrooms release their moisture, it evaporates, and both the mushrooms and onions become golden brown and caramelized—about 8 to 10 minutes.
- Stir in the remaining butter, then add the minced garlic and Dijon mustard. Cook for about 1 minute until fragrant.
- Pour in the broth (or wine), lemon juice, and lemon zest. Let the mixture simmer and bubble for about a minute to meld the flavors.
- Remove the skillet from heat. Stir in the Parmesan cheese and chopped parsley.
- Before draining the pasta, scoop out 2 tablespoons of the hot pasta water and add it to the sauce. Drain the pasta and toss it into the skillet with the sauce, mixing well to coat evenly.
- Season with salt and pepper to taste, then serve immediately.
