This slow cooker steak and mushrooms is one of those set it and forget it crockpot recipes that makes weeknight dinners so much easier. I love that you can throw everything in the slow cooker in the morning and come home to a hot, tender, flavorful meal that is completely gluten free, dairy free, and keto friendly. No canned soup required!
It's just simple whole ingredients that create the most delicious savory sauce.
The steak comes out incredibly tender after slow cooking all day and the mushrooms and onions soak up all of that amazing flavor from the sauce. I like to serve this over mashed potatoes so the sauce soaks right in, but it is equally good over rice or with roasted vegetables on the side.
This is the kind of recipe that makes people think you spent all day in the kitchen when really your slow cooker did all the work.

Instructions
Cut the steaks into 4-6 serving size pieces (if it's not already cut). Layer the steak pieces into the bottom of your crockpot.
Whisk together the brown sugar, coconut aminos or soy sauce, apple cider vinegar, Worcestershire sauce and minced garlic. Pour the mixture overtop of the steak.
Evenly top the steak with sliced mushrooms and sliced onion.
Cover the slow cooker and cook on low for 4-6 hours or high for about 2 hours. The steak needs to reach an internal temperature of at least 160 degrees when done.
When done, remove steak from the crockpot and using a slotted spoon remove the onion and mushrooms. Serve immediately.
Hint: I love to serve this recipe with mashed potatoes, my Instant Pot Garlic Ginger Green Beans or my Crispy Garlic and Rosemary Smashed Potatoes.

Top Tip
If you have a few extra minutes before starting this recipe try doing a quick sear on the steak in a hot skillet before adding it to the slow cooker. Just 1-2 minutes per side in a little oil adds a beautiful depth of flavor to the finished dish. It is completely optional and the recipe is delicious without it, but it is a great way to elevate the meal when time allows.
Frequently Asked Questions
Yes! A slow cooker or crockpot is the perfect way to prepare tender and delicious steak. The internal temperature of the steak should be at least 160 degrees when it is done.
This will depend on the thickness of the steaks. Usually you can cook on high for 2-3 hours or on low for 6-8 hours. The internal temperature of the steak should be at least 160 degrees when it is done.
My favorite steaks to cook in the crockpot are round, sirloin, chuck or skirt steaks. All of these will come out tender and delicious when slow cooked.
You do not have to, and this recipe turns out delicious without that step. However if you have a few extra minutes a quick hard sear in a hot skillet before adding the steak to the crockpot adds a wonderful depth of flavor that you can only get from that browning process.
Just 1-2 minutes per side in a little oil is all it takes. Most weeknights I skip this step and go straight to the slow cooker, but it is a great option when you have the time.
Coconut aminos are my first choice in this recipe because they are gluten free and have a slightly sweeter, milder flavor than soy sauce. If you cannot use either coconut aminos or soy sauce you can try liquid aminos as a substitute, but keep in mind they tend to have more sodium so you may want to reduce any additional salt. Tamari is another good gluten free soy sauce alternative that works well in this recipe.

Thanks Gabbie! I'm so glad you enjoyed this recipe. ~Elaine
FRAN says
I am asking about seasoning, I do not use soy sauce or coconut . What could substitute them with? Thank you
smallfarmbiglife says
Hi Fran. I've only ever used coconut aminos in this recipes. I think you could probably use liquid aminos but they may have more sodium so you might need to cut down on the salt you add. I hope that helps. ~Elaine
Aaron says
Have you ever tried doing a quick hard sear on the steak before putting in crock to add that maillard flavor?
smallfarmbiglife says
Hi Aaron. Yes, I do sometimes do a sear on the steak if time allows. I don't usually add that step to my recipes to save time as most of my audience is looking for quick weeknight meals. If time allows it's a great way to add flavor to the dish. ~Elaine
