How To Make Mary Berry Horseradish Beef and Red Pepper Stir-fry
- Sear the beef: Heat 2 tbsp oil in a large frying pan. Season beef, sear in batches for 1 minute per side until browned but still pink. Remove and set aside.
- Sauté veg: Add remaining oil and shallots. Cook 5 mins over medium heat. Increase heat, add peppers and mushrooms, fry 2–3 mins.
- Add garlic and spinach: Fry garlic 30 seconds, then add spinach and cook for 1 minute until wilted.
- Finish the dish: Return beef and juices to the pan, stir in horseradish. Heat through, adjust seasoning, and serve immediately.

Recipe Tips
- Use fillet steak if preferred: It’s even more tender and cooks just as quickly.
- Cook beef in batches: Avoid overcrowding to keep it nicely browned.
- Adjust horseradish: For a milder version, reduce to 1–2 tablespoons.
- Don’t overcook beef: It should stay pink in the middle for tenderness.
- Serve hot: Best enjoyed fresh—avoid reheating or freezing.
What To Serve With Horseradish Beef Stir-fry
Serve this bold stir-fry with jasmine rice, egg noodles, or stir-fried greens. A cooling cucumber salad or a dollop of sour cream on the side can balance the heat from the horseradish.
How To Store Horseradish Beef Stir-fry
Refrigerate: Store leftovers in a sealed container for up to 1 day. Reheat quickly in a pan to avoid overcooking the beef.
Freeze: Not recommended. The texture of the beef and spinach suffers upon freezing and reheating.
