Ingredients

Scale

Meat and Vegetables

1.5 pounds lean beef strips (sirloin or flank steak), sliced thinly against the grain
1 red bell pepper, sliced into bite-sized strips
1 yellow bell pepper, sliced into bite-sized strips
1 green bell pepper, sliced into bite-sized strips
1 medium onion, sliced into bite-sized strips
3 cloves garlic, minced

Liquids and Sauce

1/4 cup vegetarian Worcestershire sauce (natural)
1/2 cup grape juice
1 cup beef broth
1 tablespoon olive oil
Freshly ground black pepper, to taste

Thickening Agent

1 tablespoon natural gelling agent (e.g., pectin, agar, carrageenan), mixed with 2 tablespoons cold water to create a slurry

Instructions

Prepare the Ingredients: Slice the beef thinly against the grain to ensure maximum tenderness. Chop the bell peppers and onion into bite-sized strips. Mince the garlic finely for strong flavor.
Sauté Beef and Vegetables: Heat olive oil in a large skillet over medium-high heat. Quickly sear the beef strips until browned on all sides, then remove and set aside. In the same skillet, sauté the onion, garlic, and bell peppers just until they begin to soften and release their sweetness.
Combine Ingredients in the Slow Cooker: Transfer the browned beef and sautéed vegetables into the slow cooker. Add the vegetarian Worcestershire sauce (natural), grape juice, beef broth, and freshly ground black pepper. Stir well to evenly combine all ingredients.
Cook Low and Slow: Cover the slow cooker and cook on low for 6 to 8 hours, allowing the beef to become tender and the flavors to meld. The low temperature helps break down the meat for perfect softness.
Thicken the Sauce: About 30 minutes before serving, mix the natural gelling agent with cold water to form a slurry. Stir the slurry into the slow cooker. Let the sauce thicken to a glossy, luscious consistency. Stir gently and allow it to finish cooking before serving.

Notes

Cut beef thinly across the grain for ideal tenderness after slow cooking.
Do not skip sautéing the beef and veggies to build rich flavor.
Use freshly ground black pepper for the best pepper steak taste.
Cook on low heat to prevent drying out and develop deep flavor.
Add the natural gelling agent slurry near the end to avoid clumpy sauce texture.
Serve with steamed jasmine rice, buttery mashed potatoes (plant-based), or egg noodles tossed in olive oil and garlic.
Garnish with fresh chopped parsley or sliced green onions for color and freshness.
Leftovers store for up to 3 days in the refrigerator or freeze for up to 3 months.
Reheat gently on stovetop or microwave with a splash of broth if sauce thickens too much.
