Step‑by‑Step Instructions for Garlic Butter Beef Bites
Step 1: Prep Steak
Begin by cutting your sirloin steak into bite-sized pieces and seasoning generously with kosher salt and black pepper. Let the seasoned beef sit for about 10 minutes, allowing the flavors to penetrate the meat. This step ensures that your Garlic Butter Beef Bites are flavorful throughout, setting the stage for a delicious dish.
Step 2: Sear Steak
In a large skillet, heat 2 tablespoons of vegetable oil over high heat until shimmering. Carefully add the seasoned steak pieces in batches, ensuring not to overcrowd the pan. Sear the beef for about 2-3 minutes until nicely browned on all sides. This browning process enhances the flavor of your Garlic Butter Beef Bites, creating a rich, savory crust.
Step 3: Transfer to Slow Cooker
Once the steak is browned, transfer it to a slow cooker. Add sliced sweet onions and minced garlic, distributing them evenly over the beef. This combination will infuse the dish with delicious aromatics. The slow cooker will help soften the onions and infuse the garlic into the steak as it cooks.
Step 4: Combine Ingredients
Pour 1 cup of unsalted beef stock over the steak mixture, ensuring everything is well-coated. Next, sprinkle the au jus gravy mix over the top, stirring slightly to combine. This mix will create a succulent sauce that enhances the flavor of your Garlic Butter Beef Bites as they simmer in the slow cooker.
Step 5: Add Butter
Place several slices of unsalted butter on top of the beef mixture in the slow cooker. The butter will melt and meld with the other ingredients, adding richness and depth to the sauce. This step elevates the comfort food experience, making your Garlic Butter Beef Bites irresistibly tasty.
Step 6: Cook
Cover the slow cooker and set it to high for 3-4 hours or low for 6-8 hours, depending on your schedule. Stir occasionally to ensure even cooking. As it simmers, your kitchen will fill with enticing aromas, letting you know that a hearty meal is on the way.
Step 7: Serve
When ready, serve the Garlic Butter Beef Bites warm over a bed of mashed potatoes, rice, or noodles. The tender beef and rich sauce create a satisfying meal that will delight your family or guests. Enjoy the delicious magic of your slow-cooked feast!

Just remember to add the butter before you start the slow cooker.

Garlic Butter Beef Bites Recipe FAQs
How do I know if my steak is ripe enough to use?
Absolutely! When selecting sirloin steak, look for cuts that are bright red with a small amount of marbling, which indicates tenderness. Avoid any pieces with dark spots or excessive sinew, as these can indicate the meat is aging or of lower quality. Fresh steak should feel firm to the touch.
What’s the best way to store leftover Garlic Butter Beef Bites?
Very! Store your leftovers in an airtight container in the refrigerator, where they’ll stay fresh for up to 3 days. When reheating, I recommend adding a splash of beef stock to keep the dish juicy and prevent it from drying out.
Can I freeze Garlic Butter Beef Bites?
Of course! For longer storage, you can freeze Garlic Butter Beef Bites. Place portions of the beef and sauce in freezer-safe bags, removing as much air as possible before sealing. They’ll stay good for up to 2 months. For easy meal prep, this option is fantastic!
What should I do if my beef turns out tough after cooking?
If your beef is tough, it might be due to cooking it at too high a temperature or not allowing enough cooking time. For ultra-tender beef, use the low setting on your slow cooker for 6-8 hours, which allows the connective tissues to break down. Additionally, ensure the beef is seared to lock in moisture and flavors.
Is this dish safe for my kids or anyone with allergies?
Great question! Garlic Butter Beef Bites are fairly safe, but it’s crucial to cater to any specific allergies. The primary allergens here would be dairy (from the butter) and possible gluten from gravy mixes. For a dairy-free option, feel free to substitute with plant-based butter and check for gluten-free au jus mixes. Always double-check ingredient labels if allergies are a concern!
Can I mix vegetables into the Garlic Butter Beef Bites?
Absolutely! Adding vegetables is encouraged. Simply chop your favorite veggies, like carrots or zucchini, and add them to the slow cooker during the final hour of cooking. This not only boosts nutrition but also enhances the flavor profile, making the dish even more delectable!
