- Sprinkle the steak with black pepper and set aside in a covered dish.
- In the same skillet, add the sliced onion and cook until softened.
- Deglaze the pan with 3 tablespoons of wine vinegar, scraping up any browned bits.
- Stir in 4 teaspoons of Dijon mustard and 1/4 cup of low salt beef broth.
- Simmer until the sauce thickens slightly, then pour over the rested steak to serve.
Tips & Substitutions
To enhance the flavor of your sirloin steak, consider marinating it in the olive oil, black pepper, and a splash of vinegar for a few hours before cooking. If you need a substitute for Dijon mustard, try using whole grain mustard for added texture. For a touch of sweetness, add a teaspoon of honey to the sauce. This recipe pairs beautifully with A 3-Bean Bake.
Serving Suggestions
Serve the sirloin steak topped with the onion-mustard sauce alongside roasted vegetables or a fresh salad for a balanced meal. This dish pairs well with mashed potatoes or rice to soak up the delicious sauce. For a complete dinner, consider serving it with a slice of Frypan Pizza as a fun side.
Storage & Reheating
Leftover steak can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, gently warm the steak in a skillet over low heat until heated through, adding a splash of beef broth to maintain moisture. For best results, avoid microwaving as it can dry out the steak.

Frequently Asked Questions
Can I use a different cut of meat for this recipe?
Yes, while sirloin steak is recommended for its flavor and tenderness, you can substitute it with ribeye or flank steak. Just adjust the cooking time based on the thickness of the meat to ensure it's cooked to your desired doneness.
How can I make this sauce more flavorful?
To boost the flavor of the sauce, consider adding minced garlic or fresh herbs like thyme or rosemary while the onions are cooking. A splash of Worcestershire sauce can also deepen the umami profile, making it even more delicious.
Is this recipe suitable for meal prep?
Absolutely! You can prepare the steak and sauce ahead of time. Just cook the steak to medium rare, allow it to cool, and store it separately from the sauce. When ready to eat, reheat both together for a quick and satisfying meal.
