Ingredients
 

Main Ingredients

  • 1 tbsp olive oil
  • 3 tbsp unsalted butter
  • 16 oz cremini mushrooms, thinly sliced
  • 0.75 cup finely chopped yellow onion
  • 1.5 tsp minced garlic
  • 1 tsp chopped fresh thyme
  • 3.5 tbsp all-purpose flour for thickening
  • 1 cup Guinness stout
  • 2 cup low-sodium beef broth use vegetable broth for a vegetarian version
  • 2 tsp Worcestershire sauce
  • 1 tsp soy sauce adds extra umami
  • 0.5 tsp Dijon mustard optional
  • 0.5 tsp brown sugar balances the stout’s bitterness
  • 0.75 tsp kosher salt adjust to taste
  • 0.5 tsp freshly ground black pepper
  • 2 tbsp heavy cream optional for a silkier finish

Instructions

Preparation Steps

  • Warm the olive oil and 1 tbsp butter in a large skillet over medium-high heat.
  • Add mushrooms and cook, stirring occasionally, until deeply browned, 7–9 minutes.
  • Stir in the remaining butter and the onion. Cook until softened, about 3 minutes.
  • Add garlic and thyme; cook until fragrant, about 30 seconds.
  • Sprinkle flour over the vegetables. Stir well and cook 2 minutes to form a blond roux.
  • Pour in the Guinness, scraping the pan to release browned bits.
  • Whisk in broth, Worcestershire, soy sauce, Dijon, and brown sugar. Bring to a gentle simmer.
  • Simmer, stirring now and then, until thick and glossy, 8–10 minutes.
  • Stir in heavy cream. Season with salt and pepper. Adjust thickness with a splash of broth if needed.

Notes

Variation: Swap beef broth with vegetable broth and 1 tsp miso for a rich vegetarian option. Serving tip: Keep warm in a small slow cooker for holiday buffets. Leftovers thicken as they cool—thin with a little warm broth when reheating.
