Can I Prepare This Dish in Advance?

Yes, preparing this dish in advance is a great way to enhance the flavors. You can marinate the steak overnight in the refrigerator, which allows the mustard and sugar mixture to penetrate deeply, enriching the overall taste.

Slow Cooker Nanny’s Braised Steak Ingredients

• 1 kg of Oyster Blade steak (or any affordable casserole-style steak)
• 3 tablespoons of creamy bottle-style mild American mustard
• 3 tablespoons of brown sugar
• 2 heaped tablespoons of plain flour
• Salt and pepper, to taste
• 1/2 cup of tomato sauce or ketchup (low sugar or regular as preferred)
• 1/8 cup of soy sauce (reduced salt or regular as preferred)
• 1 large brown onion, thinly sliced

How To Make Slow Cooker Nanny’s Braised Steak

1. Prepare the marinade: In a large plastic freezer bag, combine the creamy bottle-style mild American mustard and brown sugar, mixing them well together.
2. Coat the steaks: Place the Oyster Blade steak into the bag with the mustard and sugar mixture, tossing and rubbing the steaks to ensure they are evenly coated.
3. Prepare the flour mixture: In another large plastic freezer bag, add the plain flour seasoned generously with salt and pepper, and shake the bag to mix the ingredients thoroughly.
4. Dredge the steaks: Transfer the mustard and sugar-coated steaks from the first bag into the flour mixture bag, tossing them around to fully dust each steak with flour.
5. Layer in the slow cooker: Remove the flour-dusted steaks from the bag and arrange them in the slow cooker, trying to keep them in a single layer if possible.
6. Add the onions: Evenly distribute the thinly sliced brown onion over the steaks laid out in the slow cooker.
7. Combine the sauces: In a small mixing bowl, blend together the tomato sauce or ketchup and soy sauce, then pour this mixture evenly over the steaks and onions.
8. Cook: Set your slow cooker to the LOW setting and let the steaks cook undisturbed for 5 hours.

How Do I Know When the Steak is Properly Cooked?

The steak is properly cooked when it is tender enough to be easily pulled apart with a fork. This usually happens after about 5 hours on low heat in a slow cooker, ensuring the meat is both tender and flavorful.

Recipe Tips

• Monitor the sauce thickness: Check the consistency of the sauce an hour before finishing; if too thin, leave the lid ajar to allow some evaporation and thickening.
• Enhancing flavor: For a deeper flavor profile, consider browning the steaks in a skillet before slow cooking; this adds a rich, caramelized texture to the meat.
• Onion alternatives: If you’re not a fan of brown onions, try using red onions or shallots for a milder taste that complements the steak without overpowering.
• Mustard variety: Experiment with different types of mustard for a twist on flavor; spicy brown mustard or Dijon can add a unique zest to your dish.

Recipe Variations

• Gluten-free adaptation: Replace the plain flour with any gluten-free flour or cornstarch to make this recipe suitable for those with gluten sensitivities.
• Low-sodium option: Use low-sodium versions of both the tomato sauce and soy sauce, and limit the added salt to control the sodium content for a heart-healthier dish.
• Spicy kick: Add a tablespoon of crushed red pepper flakes or a few dashes of hot sauce to the sauce mixture if you prefer a bit of heat in your meals.
• Sweet variation: Introduce a tablespoon of honey to the sauce to balance the savory elements with a subtle sweetness that complements the mustard and ketchup.

What To Serve With Nanny’s Braised Steak

Serve Nanny’s Braised Steak with sides like garlic parmesan roasted broccoli, creamy polenta, or apple walnut salad.

A side of rosemary focaccia bread or caramelized Brussels sprouts complements the steak well. You can also pair it with a tangy beetroot salad or roasted sweet potatoes.
