Ingredients You’ll Need

Save

Here is your shopping list. No exotic, hard-to-find ingredients that will sit in your pantry for the next decade, I promise.

• 1.5 lbs Flank Steak or Sirloin: Slice it thin, against the grain. Cutting against the grain is non-negotiable unless you enjoy chewing on leather.
• 2 Large Bell Peppers: Green and red look pretty, but grab whatever color is on sale.
• 1 Medium Onion: Sliced into strips. Try not to cry; it’s just dinner.
• 1/2 cup Beef Bone Broth: Regular beef broth works too, but bone broth gives it that “I boiled this for 48 hours” depth.
• 1/4 cup Soy Sauce or Coconut Aminos: For that essential salty, savory backbone.
• 2 tablespoons Apple Cider Vinegar: Just a splash to cut through the richness.
• 3 cloves Garlic: Minced. And yes, you can measure this with your heart.
• 1 teaspoon Fresh Ginger: Grated. Or use the squeeze tube stuff, no judgment here.
• 1/2 teaspoon Xanthan Gum: Our secret weapon to thicken the sauce without using carbs.
• Salt and Black Pepper: To taste, obviously.

Step-by-Step Instructions

1. Prep the Beef: Slice your steak into thin strips. Toss them into the bottom of your crock pot.
2. Chop the Veggies: Slice your peppers and onions into thick strips. Don’t slice them too thin, or they will dissolve into mush by hour six. Toss them right on top of the beef.
3. Whisk the Sauce: In a small bowl, whisk together the beef broth, soy sauce, apple cider vinegar, garlic, and ginger. Pour this liquid gold all over the meat and veggies.
4. Set and Forget: Pop the lid on. Cook on Low for 5 to 6 hours or on High for 3 to 4 hours. Walk away and live your life.
5. Thicken it Up: About 20 minutes before serving, ladle a few tablespoons of the hot broth into a cup, whisk in the xanthan gum until smooth, then stir it back into the crock pot. Let it simmer for the remaining time to thicken beautifully.

Common Mistakes to Avoid

• Dumping the xanthan gum straight in: If you just toss the powder into the crock pot, it will clump into weird, gelatinous space-alien pods. Always mix it with a little warm liquid first.
• Opening the lid every 20 minutes: Every time you peek, you lose about 15 minutes of cooking heat. Resist the urge. Trust the process.
• Using super lean meat: Lean beef turns into cardboard in a slow cooker. You want a little fat marbling to keep things juicy.
• Overcooking the veggies: If you leave this on low for 11 hours while you go to work, your peppers will look like green sludge. Stick to the time frame, FYI.

Alternatives & Substitutions

Don’t have flank steak? No problem. Sub in chuck roast or top sirloin. Just make sure to trim any massive chunks of hard fat so your sauce doesn’t turn into an oil slick.

If soy sauce isn’t your jam or you are strictly avoiding gluten, coconut aminos are a fantastic swap. It adds a subtle sweetness that actually mimics traditional brown sugar pepper steak remarkably well. Want a little kick? Throw in a pinch of red pepper flakes or a squirt of sriracha. IMO, a little heat makes everything better, but you do you.

FAQ

Can I use cornstarch instead of xanthan gum?

Well, technically yes, but why invite those extra carbs to the party? If you aren’t strictly low carb, a tablespoon of cornstarch mixed with cold water will thicken the sauce beautifully.

What should I serve this over?

Are you trying to keep it keto? Riced cauliflower or zoodles are your best friends here. If you don’t care about carbs and just want pure comfort, pile it high on top of a mountain of jasmine rice or mashed potatoes.

Can I freeze this recipe?

Absolutely. You can dump all the raw ingredients and sauce into a gallon freezer bag and freeze it for up to three months. Just thaw it in the fridge overnight before dumping it into the crock pot. Easy peasy.

My sauce is too watery, what did I do wrong?

Slow cookers trap all the moisture, so vegetables release a lot of water. If the xanthan gum didn’t thicken it enough, take the lid off and run the crock pot on High for 20-30 minutes to let some of that liquid evaporate.

Can I make this in an Instant Pot instead?

You sure can. Cook it on High Pressure for 12 minutes, then do a quick pressure release. Stir in your thickener at the end using the sauté function.

Final Thoughts

There you have it. A deeply comforting, insanely delicious low carb pepper steak that basically cooks itself while you do literally anything else.
