Slow Cooker Beef and Pepper Steak

This slow cooker pepper steak features tender beef and sweet vegetables in a rich, thickened gravy. It is an efficient meal for busy schedules that requires minimal active cooking time.

List of ingredients

• 2 pounds beef sirloin – cut into 2 inch strips for uniform cooking.
• 2-3 garlic cloves – sliced thin to release aromatic oils without overpowering.
• 3 tablespoons olive oil – used for searing the beef to develop a crust.
• 2 tablespoons Montreal steak seasoning – a blend of herbs and spices for deep flavor.
• 1/4 cup water – combined with cornstarch for the thickening agent.
• 1/2 cup beef broth – provides a savory liquid base for the sauce.
• 2 tablespoon cornstarch – used to create a thick, glossy gravy.
• 1/2 onion – sliced into strips to provide natural sweetness.
• 2 large red bell peppers – cut in half and sliced into strips for color and flavor.
• 3 medium ripe tomatoes – cubed to add acidity and body to the sauce.
• 3 tablespoons soy sauce – adds umami and saltiness to the profile.
• 1 teaspoon white sugar – balances the acidity of the tomatoes.
• salt and pepper – added to taste for final seasoning.

step-by-step instructions

1. Prepare and Season: Trim any excess fat from the beef sirloin. Season both sides of the meat generously with Montreal steak seasoning.
2. Sear the Beef: Heat olive oil in a cast iron skillet or large pan over medium heat. Brown the steak on both sides until a deep color is achieved, then slice into 2-inch strips and transfer them to the crock pot.
3. Create the Slurry: Whisk the water and cornstarch together until smooth. Pour this mixture directly into the slow cooker.
4. Combine Ingredients: Stir in the beef broth, sliced garlic, bell peppers, cubed tomatoes, sliced onion, soy sauce, sugar, salt, and pepper. Mix well to ensure all ingredients are coated.
5. Slow Cook: Cover the crock pot with a tight lid. Cook on the High setting for 3 to 4 hours, or on the Low setting for 6 to 8 hours.
6. Serve: Dish the pepper steak over hot spaghetti, sticky rice, or creamy mashed potatoes.

Expert Tips for Maximum Tenderness

Cut Beef Against the Grain

Locate the muscle fibers running through the steak strips before slicing. Slice perpendicular to these lines to ensure the meat is easy to chew. This process shortens the fibers, preventing the steak from feeling tough after slow cooking.

Sear the Meat First

Browning the beef in a hot skillet creates a Maillard reaction, which develops complex flavor compounds. This step locks in moisture and prevents the beef from looking gray. A cast iron skillet is recommended for the most consistent heat.

Choose the Right Beef Cut

Sirloin is an excellent choice for this recipe because it balances tenderness with flavor. If you prefer a more budget-friendly option, you can use chuck roast. Chuck roast requires the longer “Low” cooking time to break down tougher connective tissues.

Customizing Your Ingredients

Use Different Colored Bell Peppers

Red bell peppers are the traditional choice due to their sweetness. However, you can use green, yellow, or orange peppers depending on your preference. Green peppers offer a more bitter, earthy tone, while yellow and orange remain sweet.

Incorporate Additional Vegetables

You can increase the nutritional value by adding other hearty vegetables to the pot. Sliced carrots, mushrooms, or cauliflower florets work well in this sauce. Add broccoli during the last hour of cooking to prevent it from becoming too mushy.

Swap Tomatoes for Fire-Roasted Versions

For a deeper, smokier flavor profile, use canned fire-roasted diced tomatoes instead of fresh ones. This adds a charred note that complements the seared beef. Ensure you drain excess liquid if the canned tomatoes are very watery.

Perfecting the Sauce Consistency

Creating a Proper Cornstarch Slurry

Always mix cornstarch with a cold liquid like water before adding it to the pot. Adding dry cornstarch directly to hot liquid will cause clumps that are difficult to remove. Whisk until the mixture is completely smooth.

Adjusting the Thickness

If the sauce is too thin after cooking, leave the lid off and cook on High for an additional 30 minutes. If the sauce is too thick, stir in a tablespoon of beef broth or water. The consistency should be thick enough to coat the back of a spoon.

Balancing the Flavor Profile

Taste the sauce before serving to ensure the balance of salt and sweet is correct. If it tastes too acidic from the tomatoes, add a pinch more sugar. If it needs more depth, add a small splash of additional soy sauce.

Recommended Side Dishes

Serve with Mashed Potatoes

Creamy mashed potatoes are an ideal base because they absorb the thick gravy. Use butter and a splash of milk for a fluffy texture. This combination makes the meal feel more substantial and comforting.

Pair with Steamed Rice

Sticky white rice or brown rice provides a neutral base that lets the flavors of the pepper steak shine. The rice grains soak up the savory soy-based sauce. For a twist, try using jasmine or basmati rice for a floral aroma.

Use Egg Noodles or Spaghetti

Pasta is a great alternative for those who prefer a heartier texture. Toss the noodles in a small amount of olive oil or butter before adding the steak on top. This prevents the pasta from sticking together.

Low Carb Alternatives

For a lower carbohydrate option, serve the beef and peppers over cauliflower rice. Steamed sautéed spinach or a side of roasted zucchini also pairs well. These options maintain the flavor of the dish while reducing the calorie count.

Storage and Make-Ahead Guidance

Refrigerator Storage

Store leftover pepper steak in an airtight glass or plastic container. Keep it refrigerated for up to three days. Ensure the container is completely sealed to prevent the beef from absorbing other fridge odors.

Freezing Instructions

This recipe is freezer-friendly and can be stored for up to three months. Allow the dish to cool completely to room temperature before transferring it to a freezer-safe bag or container. Remove as much air as possible from the bag to prevent freezer burn.

Thawing Process

Thaw frozen pepper steak slowly in the refrigerator overnight. Avoid thawing it on the counter to maintain food safety. Once thawed, it can be reheated using the methods described below.

Proper Reheating Techniques

Microwave Reheating

For individual portions, place the steak in a microwave-safe dish. Cover it with a damp paper towel to keep the moisture in. Heat in short intervals, stirring every minute until the center is hot.

Stovetop Reheating

For larger quantities, transfer the leftovers to a skillet over medium-low heat. Add a small splash of beef broth or water to loosen the sauce. Stir occasionally until the dish is heated through completely.

Troubleshooting Common Issues

Fixing a Runny Sauce

If the sauce remains watery after the recommended cooking time, mix one teaspoon of cornstarch with a tablespoon of cold water. Stir this mixture into the crock pot and cook on High for 15 to 20 minutes. This will quickly tighten the gravy.

Preventing Mushy Vegetables

If you prefer your bell peppers to have a bit of a crunch, do not add them at the beginning. Add the sliced peppers halfway through the cooking process. This ensures they are cooked but still hold their shape.

Managing Over-Salted Sauce

If the soy sauce and steak seasoning make the dish too salty, add a few cubed raw potatoes to the pot for the last hour. The potatoes will absorb some of the excess salt. Remove the potatoes before serving.

Frequently Asked Questions

Can I use a different beef cut?

Yes, you can use chuck roast or stew meat. If using a tougher cut like chuck, ensure you cook on the Low setting for the full 8 hours to ensure the meat becomes tender.

Do I have to sear the meat first?

While you can put the meat in raw, searing is highly recommended. Searing adds a depth of flavor and a browned texture that cannot be replicated by the slow cooker alone.

Is it possible to make this dairy-free?

Yes, this recipe is naturally dairy-free as it uses olive oil and beef broth. Ensure your steak seasoning is free from any dairy additives to keep it completely dairy-free.

Can I use a different type of oil for searing?

You can use any oil with a high smoke point, such as avocado oil or canola oil. Avoid using extra virgin olive oil on very high heat, as it can smoke and change the flavor.

What if I don’t have Montreal Steak Seasoning?

You can make a substitute by mixing salt, black pepper, garlic powder, onion powder, and a pinch of paprika. Use about two tablespoons of this homemade blend to replace the store-bought seasoning.
