Step 1: Sauté the onions and garlic
- Heat the olive oil and butter in a large frying pan over medium heat. Add the chopped onions and minced garlic, and sauté for 5-7 minutes until softened and golden.
Step 2: Cook the beef strips
- Add the beef strips to the pan and cook for 3-4 minutes until browned all over but still tender. Remove the beef from the pan and set it aside.
Step 3: Sauté the mushrooms
- In the same pan, add the sliced mushrooms and cook for 5 minutes until they release their moisture and start to brown.
Step 4: Create the sauce
- Pour in the beef stock, mustard, and smoked paprika. Stir well and bring the mixture to a simmer for 2-3 minutes. Return the beef to the pan and stir in the sour cream, cooking for another 2-3 minutes until the sauce thickens.
Step 5: Season and serve
- Season with salt and pepper to taste. Remove from heat and serve the Hairy Bikers Beef Stroganoff over rice or noodles. Garnish with fresh parsley if desired.
