How to Make Slow Cooker Beef Steak with Mushrooms and Onion Gravy

Follow these simple steps to prepare tender, flavorful beef steak right in your crockpot.

Step 1: Prepare the Beef

Start by patting the beef steaks dry with paper towels. If the steaks are particularly large, cut them into smaller serving-sized pieces.

Season both sides with salt, black pepper, paprika, and dried thyme.

I usually like to season the beef generously because it adds flavor throughout the cooking process.

Step 2: Brown the Beef (Optional but Recommended)

Heat olive oil in a large skillet over medium-high heat.

Add the seasoned beef steaks and sear them for approximately 2–3 minutes per side until nicely browned.

You don’t need to cook the beef all the way through. The goal is simply to develop a beautiful brown crust.

Honestly, this extra step makes a noticeable difference in the final flavor. However, if you’re short on time, you can skip it and place the seasoned beef directly into the slow cooker.

Step 3: Prepare the Mushrooms and Onions

Place the sliced mushrooms and chopped onions into the bottom of your slow cooker.

Add the minced garlic and spread everything evenly.

These vegetables will cook slowly in the flavorful beef juices, becoming soft and delicious while helping create the base for the gravy.

Step 4: Add the Beef

Arrange the browned beef steaks over the mushrooms and onions.

Try to spread the pieces out evenly so they cook consistently.

Step 5: Make the Gravy Mixture

In a medium-sized bowl, whisk together:

• Beef broth
• Worcestershire sauce
• Tomato paste
• Soy sauce, if using
• A little additional black pepper

Mix until the tomato paste is completely incorporated.

Pour this mixture over the beef and vegetables.

The liquid should surround the beef without necessarily covering every piece.

Step 6: Slow Cook Until Tender

Cover the slow cooker with its lid.

Cook using one of these settings:

• LOW: 6–8 hours
• HIGH: 3–4 hours

Cooking times can vary depending on your slow cooker and the thickness of the beef.

For the best results, I recommend using the LOW setting. The slower cooking process gives tougher cuts of beef more time to become tender.

The beef should be fork-tender when finished.

Step 7: Thicken the Gravy

Once the beef is tender, carefully transfer the steaks to a plate and keep them warm.

In a small bowl, combine cornstarch and cold water. Stir until smooth.

Pour the slurry into the slow cooker and stir it into the cooking liquid.

Cover and cook on HIGH for another 10–15 minutes, or until the gravy thickens.

If you prefer a thinner gravy, simply use less cornstarch.

Step 8: Serve and Enjoy!

Return the beef steaks to the slow cooker and spoon the mushroom and onion gravy over the top.

Garnish with fresh chopped parsley if desired.

Serve warm with your favorite side dishes, and don’t forget to add plenty of that delicious gravy!

Cooking Tips for the Best Slow Cooker Beef Steak

1. Choose the Right Cut of Beef

Chuck steak, blade steak, and round steak are all good options for this recipe.

Chuck steak is especially nice because its connective tissue breaks down during slow cooking, helping create a tender, flavorful result.

2. Don’t Skip Browning If You Have Time

Although browning isn’t essential, it adds a deeper, richer flavor to the finished dish.

Those browned bits left in the skillet are full of flavor, so you can add a splash of beef broth to the skillet and scrape them into your slow cooker.

3. Avoid Adding Too Much Liquid

Slow cookers trap moisture, and the beef and vegetables will release additional liquid as they cook.

You don’t need to completely submerge the steaks in broth.

4. Slice Mushrooms Thickly

I prefer cutting mushrooms into thicker slices because they hold their shape better during several hours of cooking.

Very thin slices can become overly soft.

5. Don’t Keep Opening the Lid

Every time you remove the slow cooker lid, heat escapes and cooking time increases.

It’s best to let everything cook undisturbed until the recommended cooking time is nearly finished.

6. Adjust the Gravy to Your Taste

If you like a thicker gravy, add a little more cornstarch slurry.

For a richer flavor, you can stir in a small knob of butter just before serving.

What to Serve with Slow Cooker Beef Steak

This beef steak and mushroom gravy recipe pairs beautifully with simple, comforting side dishes.

Here are some of my favorite serving ideas:

• Creamy mashed potatoes: Probably my favorite option! The potatoes soak up all that rich brown gravy.
• Steamed white rice: A simple and filling side that works wonderfully with the savory sauce.
• Egg noodles: Toss the noodles with a little butter and serve the beef and gravy over the top.
• Roasted vegetables: Carrots, green beans, broccoli, and Brussels sprouts add freshness to the meal.
• Buttered dinner rolls: Perfect for soaking up every last bit of gravy.
• Garlic bread: A delicious addition if you want something extra comforting.

Storage and Reheating Instructions

How to Store Leftovers

Allow the beef and gravy to cool slightly, then transfer everything into an airtight container.

Refrigerate for up to 3–4 days.

For food safety, refrigerate leftovers within 2 hours of cooking.

Can You Freeze Slow Cooker Beef Steak?

Absolutely!

Place the cooled beef and gravy into freezer-safe containers or bags.

Freeze for up to 3 months for the best quality.

Thaw overnight in the refrigerator before reheating.

How to Reheat

For stovetop reheating, place the beef and gravy in a saucepan over medium-low heat.

Add a splash of beef broth if the gravy has thickened too much.

Cover and heat until thoroughly hot, stirring occasionally.

You can also reheat individual portions in the microwave, stirring the gravy halfway through heating.

Recipe Variations

Want to change things up? Here are a few easy ways to customize this recipe.

• Add carrots: Include sliced carrots for extra sweetness and color.
• Make it creamier: Stir in a little heavy cream near the end of cooking.
• Add potatoes: Place baby potatoes or chopped Yukon Gold potatoes around the beef for a complete one-pot meal.
• Use onion soup mix: Replace some of the individual seasonings with a packet of dry onion soup mix for a convenient flavor boost. Adjust the salt accordingly.
• Add fresh herbs: Rosemary and thyme both pair beautifully with slow-cooked beef.
• Make it gluten-free: Use certified gluten-free beef broth and Worcestershire sauce, and check all seasoning labels.

Frequently Asked Questions

1. Can I put raw beef steak directly into the slow cooker?

Yes! You can place seasoned raw beef directly into the slow cooker without browning it first. Browning is optional, but it adds extra flavor and creates a richer taste.

2. Why is my slow cooker beef steak tough?

Beef can remain tough if it hasn’t cooked long enough for the connective tissue to break down. This is especially common with tougher cuts such as chuck and round steak. Give it additional cooking time until it becomes fork-tender.

3. Can I cook this beef steak recipe overnight?

Technically, yes, provided your slow cooker has a suitable LOW setting and a reliable temperature control. However, I recommend following the 6–8-hour cooking time and using a programmable slow cooker if you need to schedule dinner ahead of time. Avoid leaving the beef cooking excessively long, as it can become dry.

4. Can I use canned mushrooms instead of fresh mushrooms?

Yes! Canned mushrooms work if that’s what you have available. Drain them well before adding them to the slow cooker. Fresh mushrooms generally provide a better texture and flavor, but canned mushrooms are a convenient alternative.

5. Can I make the gravy thicker without cornstarch?

Yes. You can use an equal amount of flour mixed with cold water to make a smooth slurry. Add it gradually to the cooking liquid and allow it to cook until thickened. Alternatively, you can reduce the gravy in a saucepan on the stovetop.
