Before you start
Before starting, slice the mushrooms uniformly so they cook at the same rate. Mince the garlic cloves finely and chop the fresh parsley.
Cut the beef into equal bite-sized cubes and pat them completely dry with paper towels. Dry meat sears much better than damp meat. Measure out the heavy cream and butter, and let them sit briefly to take the chill off.
Ingredients at a glance (7)
- 1 1/2 lbs beef sirloin, cut into bite-sized cubes
- 1 tsp kosher salt and 1/2 tsp black pepper
- 2 tbsp unsalted butter
- 3 cloves garlic, minced
- 8 oz cremini mushrooms, sliced
- 1 cup heavy cream
- 2 tbsp fresh parsley, chopped
Instructions
Searing the Beef to Perfection
- Season the BeefPat the beef cubes completely dry with paper towels. Season all sides of the meat evenly with kosher salt and black pepper, pressing the seasoning gently into the meat so it adheres well.Look for The beef cubes should be evenly coated with seasoning on all sides.Tip Dry beef is essential for getting a beautiful brown crust when searing.
- Sear the BeefHeat a cast iron skillet over high heat. Add the seasoned beef cubes in a single layer and sear without moving for 2 minutes to develop a rich crust. Toss and cook for another 2 minutes until the internal temperature reaches 145°F (63°C). Transfer the beef to a plate and let it rest for at least 3 minutes.Look for The beef will have a deep, golden-brown crust and reach a safe internal temperature.Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)Tip Avoid crowding the skillet; cook in batches if needed to prevent steaming.
The beef cubes should have a deep, golden-brown crust on the outside while remaining tender. Sizzling sounds will be loud and active in the skillet. A rich, savory aroma of caramelized meat will fill the kitchen. Ensure the meat is transferred to a plate to rest, keeping the pan drippings in the skillet for the next phase.
Sautéing Mushrooms in Garlic Butter
- Sauté the GarlicReduce the heat to medium. Add the unsalted butter to the same skillet, letting it melt and foam. Stir in the minced garlic and cook for about 30 seconds until fragrant, scraping up the browned bits from the beef.Look for The garlic will turn golden and smell highly aromatic without burning.Tip Keep the garlic moving constantly so it does not scorch in the hot pan.
- Cook the MushroomsAdd the sliced cremini mushrooms to the garlic butter. Sauté for 5 to 6 minutes, stirring occasionally, until the mushrooms release their moisture, shrink slightly, and develop a beautiful golden-brown color.Look for The mushrooms will be tender, golden, and coated in garlic butter.Tip Let the mushrooms cook undisturbed for a minute at a time to promote browning.
The mushrooms will shrink slightly, turning a beautiful golden-brown color as they absorb the garlic butter. You will hear a gentle sizzling sound and smell the fragrant, warm aroma of toasted garlic. The bottom of the skillet will be coated with a mixture of melted butter and caramelized mushroom juices, ready for the cream.
Simmering the Cream Sauce
- Simmer the CreamPour the heavy cream into the skillet with the mushrooms. Bring the mixture to a gentle simmer over medium-low heat. Let it bubble softly for 3 to 4 minutes until the sauce reduces slightly and thickens into a rich gravy.Look for The cream will thicken enough to coat the back of a wooden spoon.Tip Simmer gently; boiling heavy cream too vigorously can cause the sauce to separate.
- Combine and GarnishReturn the seared beef cubes and any accumulated juices to the skillet. Stir gently to coat the meat in the warm cream sauce. Garnish the finished dish with fresh chopped parsley and serve immediately.Look for The dish is hot, the meat is fully coated, and the parsley adds a vibrant green contrast.Tip Serve directly from the skillet to keep the comfort meal piping hot.
The heavy cream will bubble gently, reducing and thickening into a rich, velvety gravy that easily coats the back of a spoon.
The sauce will turn a light tan color as it incorporates the browned bits from the bottom of the skillet. The dish is complete when the rested beef is folded back in and garnished with fresh green parsley.
Common mistakes
One common mistake is crowding the skillet when searing the beef. If too many pieces of meat are added at once, the pan temperature drops, causing the beef to release moisture and steam instead of sear.
Cook the beef in batches if necessary. Another error is burning the garlic; add the garlic just before the mushrooms to prevent it from turning bitter.
How to tell it’s done
The beef is perfectly cooked when it reaches an internal temperature of 145°F (63°C) on an instant-read thermometer and has rested for at least 3 minutes.
The sauce is done when it thickens to a gravy-like consistency, bubbling gently around the edges of the skillet. It should easily coat the beef and mushrooms without looking watery or separating.
- Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
