Ingredients

Instructions

Preparing the meat:

1. Lightly pound the sirloin slices with a meat mallet (ideally through plastic wrap, so you do not damage the fibers) to a thickness of about 1/4–3/8 inch (0.5–1 cm).
2. Important step: With a sharp knife, make several shallow cuts around the edge of each slice of meat. This stops the meat from curling while it sears.
3. Season the pounded, scored slices on both sides with salt and freshly ground black pepper.
4. Spread a thin layer of mustard on one side of each slice (about 4 teaspoons in total).
5. Put the flour on a shallow plate. Coat each slice thoroughly on both sides in the flour (the mustard side too). Gently shake off the excess flour.

Searing and building the base:

6. Set out a large, heavy-bottomed skillet or pot in which you can both sear and braise the meat. Over medium-high heat, heat a generous amount of vegetable oil.
7. Carefully place the coated slices into the hot oil (do not crowd the pan). Sear them quickly on each side for about 2 to 3 minutes, until nicely golden brown.
8. Remove the seared meat from the pan and set it aside on a plate for now.
9. Add the finely chopped onion to the drippings in the pan. If there is too little fat, add a little more oil. Sauté the onion over medium heat until golden (about 5–7 minutes).

Braising:

10. Add 1 teaspoon of mustard and the crushed caraway to the sautéed onion. Stir and cook briefly (about 30 seconds) until fragrant.
11. Return the seared slices to the pot or pan, on top of the onion base.
12. Pour in the hot water or broth (about 2 1/2 cups / 600 ml) so the meat is almost covered. If you use water, add the beef bouillon cube as well.
13. Bring to a boil, then reduce the heat to the lowest setting, cover with a lid and let the meat braise slowly until tender. This usually takes about 60 minutes, but the time depends on the quality and thickness of the meat. Check from time to time that there is enough liquid and add a little hot water or broth if needed. At the end the meat should be tender enough to fall apart under a fork.
14. The gravy should thicken naturally during braising thanks to the flour on the meat. If it seems too thin, you can take the meat out and simmer the gravy briefly without the lid to reduce it, or lightly thicken it with a little flour stirred into cold water (a roux is usually not needed).

Finishing and serving:

15. When the meat is tender, lift it out of the gravy. Season the gravy with salt and pepper if needed. You can strain it through a sieve for a smoother consistency, but it is not necessary.
16. Serve the sirloin slices topped with the onion gravy. Steamed rice or classic bread dumplings are the best sides.
17. Before serving, you can garnish the beef with freshly chopped parsley.

Tips

1. Use quality beef such as sirloin or strip steak. Pound the slices lightly through plastic wrap and do not forget to score the edges, so they do not curl during searing. Brushing with mustard before coating in flour adds great flavor.
2. Coat the meat only in all-purpose flour, then sear it quickly in oil on both sides until golden. This browning is important because it gives the gravy its color and flavor.
3. The base of the gravy is deeply browned onion in the meat drippings, flavored with a spoonful of mustard and caraway. Return the meat to the pot, add hot water or broth and braise slowly under a lid over low heat for at least an hour, until completely tender.
4. The gravy usually thickens by itself from the flour on the meat. If needed, let it reduce a little at the end. Serve it the classic way with steamed rice or homemade bread dumplings, generously covered in the fragrant onion gravy.

This recipe for classic beef sirloin in onion gravy is worth saving. It gives you hearty flavor and tender meat.

Frequently Asked Questions (FAQ)

• How long does beef sirloin in onion gravy keep in the fridge? In a well-sealed container it keeps for 2–3 days.
• What can I use instead of sirloin? You can use another tender cut of beef, such as top round or tenderloin, with a similar braising time.
• Why is my beef tough? Toughness can come from braising too briefly or using an unsuitable cut. The meat needs enough time to soften in liquid at a low temperature.
• Can I make it ahead and reheat it? Yes, it is often even tastier the next day. Just reheat it gently over low heat or in the oven.
• What does “na prírodno” (plain-style) mean? The meat is braised in its own juices with a base of browned onion, without tomatoes, cream or vegetables. That is exactly how this mustard and caraway onion sirloin is made.
• What cut of beef should I buy? Beef sirloin or strip steak. Cut the slices about 5/8 inch (1.5 cm) thick, pound them lightly and score the edges so they do not curl during searing.
• What side dish goes with it? Most often steamed rice or bread dumplings, which soak up the onion gravy. Boiled potatoes work well too.
