Ingredients for High Protein Slow Cooker Garlic Butter Beef Bites

Alright, let’s get down to the good stuff โ€“ what you’ll need to make these amazing High Protein Slow Cooker Garlic Butter Beef Bites! Don’t worry, it’s super straightforward. I like to break it down into two parts so it’s easy to see exactly what goes where.

For the Beef Bites

This is where the magic starts. You’ll need about 3 pounds of sirloin steak. Make sure you cut it into nice, bite-sized pieces, you know, like little cubes. Don’t forget to season them up good with 2 teaspoons of kosher salt and 1 teaspoon of black pepper. Toss it all around in a big bowl so every piece gets coated. For searing, youโ€™ll need about 1 tablespoon of vegetable oil, maybe a little more if your pan gets dry. Remember, weโ€™re just searing for color here, not cooking them all the way through!

For the Slow Cooker

Now, for the slow cooker itself! You’ll want 1 small sweet onion, thinly sliced so it gets nice and tender. Then, grab about 3 cloves of garlic and slice those thinly too. For the liquid base, pour in 1 cup of unsalted beef stock. To really amp up that savory flavor, add 1 ounce packet of au jus gravy mix. And the best part? We’ll finish it off with 4 tablespoons of unsalted butter, thinly sliced, to make everything so rich and delicious.

Step-by-Step Instructions for Perfect High Protein Slow Cooker Garlic Butter Beef Bites

Alright, it’s time to make some magic! Honestly, the hardest part is cutting the beef, and even thatโ€™s not so bad. Once that’s done, your slow cooker takes over. Just follow these simple steps and youโ€™ll have delicious High Protein Slow Cooker Garlic Butter Beef Bites in no time!

Preparing the Beef

First things first, grab that big bowl and get your sirloin steak pieces in there. Sprinkle generously with that kosher salt and black pepper โ€“ really coat them well! Now, heat up your skillet over medium-high heat with a little vegetable oil. Once itโ€™s nice and hot, carefully add the seasoned steak in batches. Weโ€™re just looking for a lovely brown sear on the outside for color and flavor; we’re not trying to cook it through. Add more oil if your pan starts looking dry between batches.

Assembling the Slow Cooker

Once your beef is seared, carefully transfer it all into your 6-quart slow cooker. Donโ€™t worry about stirring too much yet. Now, toss in your thinly sliced sweet onion and garlic over the top of the beef. For the liquid, pour in that unsalted beef stock โ€“ itโ€™s the base for all that yummy goodness. Sprinkle the au jus gravy mix evenly all over everything. Finally, artfully arrange those thinly sliced butter pats right on top. It looks so fancy!

Slow Cooking and Finishing

Now for the best part: letting the slow cooker do its thing! Cover your slow cooker and let it cook. You can go with high heat for about 3-4 hours, or if you have more time, low for 6-8 hours works beautifully and makes the beef extra tender. If you can remember, give it a stir once an hour โ€“ it really helps everything meld together. Once itโ€™s done, serve these amazing High Protein Slow Cooker Garlic Butter Beef Bites piping hot with your favorite sides. Trust me, everyone will be asking for seconds!

Tips for Success with Your Garlic Butter Beef Bites

Making these High Protein Slow Cooker Garlic Butter Beef Bites is honestly pretty foolproof, but Iโ€™ve picked up a few tricks over the years to make them absolutely perfect every single time. Itโ€™s all about those little details, you know? As a meal planning specialist, Iโ€™ve learned that sometimes the simplest things make the biggest difference. First off, sirloin is great because itโ€™s lean and flavorful, but if you canโ€™t find it, a nice flank steak or even a well-trimmed chuck roast can work, though they might take a bit longer to get tender. For more tips on handling your meats like a pro, you can check out how to prepare pork chops, which shares similar principles. The sear is super important โ€“ donโ€™t skip it! Itโ€™s not about cooking the meat, just getting those lovely browned bits for extra flavor thatโ€™ll melt into the sauce. And for seasoning? Taste and adjust! The au jus mix can be salty, so start with the recommended amounts and then add more salt and pepper at the end if needed. Trust me, a little tweak here and there makes all the difference!
