Recipe Overview

Prep Time: 10 minutes
Cook Time: 25 minutes
Total Time: 35 minutes
Servings: 4
Dietary Type: Varies (can be gluten-free with modifications, see variations)

Ingredients

1/4 teaspoon salt
1/4 teaspoon pepper
1 lb sirloin steak, 3/4 inch thick
1 tablespoon butter or margarine
1 medium onion, finely chopped
3 cups sliced mushrooms
1/2 teaspoon dried thyme
2 tablespoons all-purpose flour
1 cup beef stock
1 cup milk
1 tablespoon prepared horseradish or Dijon mustard
Chopped fresh parsley (to garnish)

Equipment Needed

Large skillet
Plate

Instructions

Begin by preparing the steak. Rub both sides of the sirloin steak with salt and pepper. This simple seasoning will enhance the natural flavors of the beef.
Melt half a tablespoon of butter (or margarine) in a large skillet over high heat. Make sure the skillet is hot before adding the steak to achieve a good sear.
Brown the steak for about 2 minutes per side. This searing process is crucial for developing a rich, flavorful crust and locking in the juices.
Transfer the seared steak to a plate and set aside.
Reduce the heat to medium-high. Add the remaining half tablespoon of butter (or margarine) to the skillet.
Add the finely chopped onion, sliced mushrooms, and dried thyme to the skillet.
Cook the vegetables until the liquid is released and the mushrooms start to brown, which should take around 5-7 minutes. Stir occasionally to ensure even cooking and prevent sticking.
Sprinkle 2 tablespoons of all-purpose flour over the mushroom mixture.
Cook for 1 minute, stirring constantly. This step helps to create a roux, which will thicken the sauce.
Gradually stir in the beef stock, milk, and horseradish (or mustard). Whisk continuously to prevent lumps from forming.
Reduce the heat to low and simmer the sauce, stirring occasionally, for about 5 minutes, or until the sauce has thickened to your desired consistency.
Return the seared steak and any accumulated juices from the plate to the pan with the sauce.
Simmer the steak in the sauce for about 5 minutes, or until it reaches your desired doneness. Use a meat thermometer to check the internal temperature: 130-135°F for medium-rare, 135-145°F for medium, and 145-155°F for medium-well.
Remove the skillet from the heat and let the steak rest for 5 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful steak.
Season the sauce with more salt and pepper to taste, if desired.
Slice the steak thinly across the grain to maximize tenderness.
Serve the sliced steak with the mushroom sauce spooned generously over the top.
Garnish with chopped fresh parsley before serving.

Expert Tips & Tricks

High Heat is Key: Don’t be afraid of high heat when searing the steak. This is crucial for developing a beautiful crust and locking in the juices. Just be sure to monitor it closely to prevent burning.
Don’t Overcrowd the Pan: If your skillet is small, sear the steak in two batches to avoid overcrowding. Overcrowding can lower the temperature of the pan and prevent proper browning.
Deglaze the Pan: For an even richer sauce, consider deglazing the pan after searing the steak. Add a splash of red wine or beef broth to the hot skillet and scrape up any browned bits from the bottom. This will add depth and complexity to the flavor of the sauce.
Make-Ahead Prep: You can chop the onion and slice the mushrooms ahead of time to save time during cooking.
Thickening Issues: If the sauce isn’t thickening enough, whisk a tablespoon of cornstarch with two tablespoons of cold water and stir it into the simmering sauce. Cook for a minute or two until thickened.
Swap the Dairy: If you are dairy-free, you can substitute the milk with unsweetened almond milk or oat milk. The sauce may be slightly thinner.

Serving & Storage Suggestions

This skillet steak with mushroom sauce is delicious served with creamy mashed potatoes, roasted vegetables (such as asparagus or broccoli), or a simple green salad. For a heartier meal, consider serving it over egg noodles or rice.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm the steak and sauce in a skillet over low heat, stirring occasionally, until heated through. Avoid overheating, as this can make the steak tough. Adding a splash of beef broth or milk can help to rehydrate the sauce.

FAQs (Frequently Asked Questions)

Q: Can I use a different cut of steak?
A: Yes, you can use other tender cuts of steak, such as ribeye or New York strip. Adjust the cooking time accordingly based on the thickness of the steak.

Q: Can I use dried mushrooms instead of fresh?
A: Yes, but rehydrate them first! Soak dried mushrooms in hot water for about 20 minutes, then drain and squeeze out excess water before adding them to the skillet.

Q: How do I know when the steak is cooked to my liking?
A: Use a meat thermometer to check the internal temperature. Medium-rare is 130-135°F, medium is 135-145°F, and medium-well is 145-155°F.

Q: Can I make this sauce ahead of time?
A: Yes, you can prepare the sauce a day in advance and store it in the refrigerator. Reheat gently before adding the steak.

Q: What if I don’t have horseradish or Dijon mustard?
A: While they add a nice depth of flavor, you can omit them if necessary. You may want to add a small splash of Worcestershire sauce for a similar savory note.
