Servings
4–6 servings
Ingredients
For the steak patties:
- 500–700 g lean ground beef (90–95% lean)
- 1/3 cup oat flour or breadcrumbs (optional for binding)
- 1 egg
- 1 tbsp Worcestershire sauce
- 1 tsp garlic powder
- 1 tsp onion powder
- 1/2 tsp black pepper
- 1/2 tsp salt
- 1 tbsp chopped parsley (optional)
For the gravy:
- 1 medium onion (sliced)
- 200–250 g mushrooms (sliced)
- 2 cups beef broth (low sodium)
- 2 tbsp Worcestershire sauce
- 1 tbsp tomato paste
- 2 tsp cornstarch (mixed with 2 tbsp water for slurry)
- 2 cloves garlic (minced)
- Salt and pepper to taste
Instructions
1. Prepare the patties
Mix ground beef, egg, Worcestershire sauce, spices, and oat flour/breadcrumbs in a bowl.
Shape into 4–6 oval patties.
2. Optional searing (recommended)
Lightly sear patties in a pan for 2–3 minutes per side.
This adds deeper flavor but can be skipped for convenience.
3. Layer in slow cooker
Place onions and mushrooms at the bottom of the slow cooker.
Lay patties on top.
4. Add gravy base
In a bowl, mix beef broth, Worcestershire sauce, tomato paste, and garlic.
Pour over patties.
5. Slow cook
- Low: 6–7 hours
- High: 3–4 hours
Patties should be tender and fully cooked.
6. Thicken gravy
30 minutes before serving, add cornstarch slurry. Stir gently and let it thicken.
7. Serve
Serve hot with mashed potatoes, brown rice, quinoa, or steamed vegetables.
Recipe Notes
- Lean beef keeps it high-protein and lower fat.
- Mushrooms add natural umami and help replace heavier fats.
- You can swap beef with ground turkey for an even leaner version.
- For gluten-free: use almond flour or gluten-free breadcrumbs.
Tips for Best Results
- Don’t skip seasoning—lean meat needs strong flavor support.
- Searing patties improves texture and depth but is optional.
- Add a splash of soy sauce for extra savory richness.
- If gravy is too thick, add a bit more broth at the end.
- If too thin, extend slow cooking with lid slightly open.
