My mother-in-law said this was better than any steakhouse she's been to. The butter makes these tips so incredibly tender and flavorful

These Slow Cooker 4-Ingredient Garlic Butter Sirloin Tips are my go-to when I want something that tastes like a fancy steakhouse dinner without actually leaving the house. The sirloin tips simmer low and slow in a pool of garlicky melted butter until they’re unbelievably tender, and the simple ingredient list makes this totally weeknight-friendly. This is the kind of dish that gets those big, dramatic compliments—my own mother-in-law said it was better than any steakhouse she’s been to, and I’m not about to argue with that.

Serve these garlic butter sirloin tips right out of the slow cooker with plenty of that buttery sauce spooned over the top. They’re amazing over creamy mashed potatoes, egg noodles, or rice to soak up every drop. Add a simple green side like roasted broccoli, steamed green beans, or a tossed salad to balance the richness. Warm dinner rolls or crusty bread are perfect for mopping up the extra garlic butter, and if you like a steakhouse vibe, finish the plate with a sprinkle of flaky salt and a glass of red wine or iced tea.

Servings: 4

2 pounds beef sirloin tips, cut into 1- to 1 1/2-inch chunks, trimmed of excess fat

Pat the sirloin tips dry with paper towels to help them brown and absorb flavor. Trim any large pieces of excess fat, but leave some marbling for tenderness.

Place the sirloin tips in an even layer in the bottom of a 4- to 6-quart slow cooker. It’s okay if they overlap a bit, but try not to pile them too high in one spot so they cook evenly.

Sprinkle the kosher salt evenly over the beef. Toss lightly with clean hands or a spoon so the salt coats as many surfaces of the meat as possible.

In a small microwave-safe bowl or saucepan, gently melt the butter just until mostly liquid. It’s okay if a few small solids remain; you don’t want it boiling.

Stir the minced garlic into the warm melted butter. This helps wake up the garlic flavor so it infuses the meat while it cooks.

Pour the garlic butter mixture evenly over the sirloin tips in the slow cooker, making sure the minced garlic is distributed throughout and not just sitting on top in one spot.

Cover the slow cooker with the lid and cook on LOW for 4 to 5 hours, or until the sirloin tips are very tender when pierced with a fork. Avoid lifting the lid during the first few hours so the heat and moisture stay trapped inside.

Once the meat is tender, give everything a gentle stir to coat the sirloin tips in the garlic butter sauce. Taste a small piece and adjust the seasoning with a pinch more salt if needed.

Serve the sirloin tips hot, straight from the slow cooker, spooning plenty of the melted garlic butter and any juices over the top of the meat and your chosen side. You should see golden brown, tender beef chunks glistening with the garlic butter sauce, with visible bits of minced garlic throughout.

For easier weeknight prep, you can trim and cut the sirloin tips the night before and store them covered in the refrigerator. In the morning, just add them to the slow cooker, top with the garlic butter mixture, and turn it on before you head out for the day.

To keep this truly 4-ingredient, the base recipe sticks to sirloin tips, butter, garlic, and salt, but you can still tweak the flavor a bit. For extra richness, add a pinch of freshly ground black pepper or a small splash of Worcestershire sauce when you stir at the end (this technically adds ingredients, but you don’t have to if you want to stay strict). If you prefer less butter, you can reduce it to 3/4 cup, though the full cup gives you that steakhouse-style, ultra-saucy finish. For a slightly lighter feel, drain off a few spoonfuls of the rendered fat before serving and just keep the garlicky butter sauce. If your slow cooker runs hot, start checking at 3 1/2 to 4 hours so the meat doesn’t overcook and dry out. Food safety tips: Always start with fresh, properly refrigerated beef and keep it chilled until you’re ready to cook. Thaw frozen sirloin tips completely in the refrigerator (never on the counter) before adding to the slow cooker so they reach a safe internal temperature quickly and evenly. Cook on LOW or HIGH only with the lid on; frequently removing the lid can lower the temperature and affect both safety and tenderness. Leftovers should be cooled and refrigerated within 2 hours and eaten within 3 to 4 days, or frozen for up to 2 to 3 months. Reheat gently on the stovetop or in the microwave until steaming hot all the way through.
