Instructions
Bring a large pot of water to a boil. Add a generous pinch of salt, then add pasta and cook just to al dente, according to package directions. Drain and set aside.
While the pasta cooks, warm a large skillet over medium-high heat. Add oil and butter. When butter has melted, add onions and cook for 4-5 minutes, until very tender.
Add the mushrooms and Worcestershire sauce. Sauté for another 5-6 minutes. As they cook, the mushrooms should release some liquid, dry out again, and develop a rich brown color.
Add garlic and thyme. Cook for about 30 seconds, just until fragrant. Stir in the flour and cook for 1 minute more, just until it turns slightly brown.
Whisk in the broth, then let the mixture simmer for 2-3 minutes. The sauce should smooth out and thicken slightly.
Gently whisk in the Greek yogurt or sour cream and lemon juice, if using, then remove skillet from the heat. Sample and add salt and pepper to taste; I usually add about 1/2 teaspoon salt and 8-10 cranks of fresh-ground black pepper.
Toss the sauce with or serve on top of drained pasta. Garnish with a sprinkle of fresh parsley or thyme as desired.
