Why This Recipe Works

Dump-and-go convenience: Ten minutes of morning prep translates to a finished dinner the moment you walk back through the door.
Restaurant-quality gravy: A quick cornstarch slurry at the end transforms the cooking juices into a glossy, spoon-coating sauce without canned soup.
Budget-friendly cut: Sirloin tips (or stew beef) become meltingly tender thanks to low-and-slow moisture, giving you luxury texture on a grocery-store budget.
One-pot cleanup: Everything cooks in the ceramic insert—no extra skillets or strainers required.
Customizable thickness: Love a lakes-of-gravy situation? Add an extra cup of broth. Prefer it spoon-stand-up thick? Reduce with the lid ajar for the last 30 minutes.
Freezer hero: Double the batch; half gets devoured tonight, the other half freezes flat for a ready-made entrée next month.
Comfort-food nostalgia: The Worcestershire–soy umami combo tastes like the vintage smothered steak you grew up with, only easier.

Ingredients You'll Need

Great beef tips start with the right cut. Look for sirloin tip roast (sometimes labeled “sirloin petite roast” or “knuckle”) that’s deep red with minimal gristle. If your butcher counter is running a special on chuck-eye, that works too—just trim the larger ribbons of fat so the gravy doesn’t turn greasy. For the mushrooms, cremini give an earthier depth than white button, but either will be delicious. Yellow onions bring natural sweetness; slice them thick so they hold shape during the long cook. Beef broth is the backbone of the gravy—reach for low-sodium so you can control salt later. Tomato paste adds both umami and a subtle rosy tint; freeze the rest of the can in 1-tablespoon scoops for future recipes. Finally, keep a jar of Better-Than-Bouillon roast beef base in the fridge; a teaspoon stirred in at the end will amplify flavor if your broth is on the weak side.

How to Make Easy Slow Cooker Beef Tips with Gravy over Mashed Potatoes

Pat and Season the Beef

Start by blotting the sirloin tips with paper towels—moisture is the enemy of browning. If you have an extra seven minutes, heat a skillet over medium-high and sear the cubes in two batches; this caramelized layer translates to deeper flavor in the final gravy. Otherwise, place the beef directly into the slow cooker. Sprinkle with 1 teaspoon kosher salt, ½ teaspoon black pepper, and 1 teaspoon smoked paprika; toss to coat evenly.

Build the Aromatic Layer

Scatter the thick onion half-moons, minced garlic, and sliced mushrooms over the beef. These vegetables will exude moisture as they cook, essentially self-basting the meat and creating a natural broth.

Whisk Together the Cooking Liquid

In a 4-cup measuring cup, combine 1¾ cups low-sodium beef broth, 3 tablespoons tomato paste, 2 tablespoons Worcestershire, 1 tablespoon low-sodium soy sauce, 1 teaspoon dried thyme, and ½ teaspoon each onion powder and garlic powder. Whisk until the tomato paste dissolves completely; nobody wants a rogue brick-red blob on their plate.

Slow Cook to Tender Perfection

Pour the liquid over the beef and veggies. Cover and cook on LOW for 7–8 hours or HIGH for 4–5 hours. The meat is ready when it can be pulled apart with the gentle pressure of two forks. Resist lifting the lid more than once; every peek releases 10–15 minutes of built-up heat and steam.

Thicken the Gravy

Thirty minutes before serving, ladle ½ cup of the hot cooking liquid into a small bowl and whisk in 3 tablespoons cornstarch until smooth. Stir the slurry back into the slow cooker, replace the lid, and switch to HIGH (if it isn’t already). The gravy will tighten to a velvety consistency that coats the back of a spoon.

Taste and Adjust

Fish out a cube of beef and a spoonful of gravy. Add salt incrementally—usually ½ teaspoon more does the trick—plus a crack of fresh black pepper. If you’d like a deeper color, stir in ½ teaspoon Kitchen Bouquet or a pinch of instant espresso powder; both amplify browning without noticeable flavor.

Make the Mashed Potatoes

While the gravy thickens, peel and cube 2½ pounds Yukon Gold potatoes (their naturally buttery texture means you can get away with less butter). Boil in well-salted water until fork-tender, 12–15 minutes. Drain, then return the potatoes to the hot pot to evaporate excess moisture. Mash with 4 tablespoons softened butter, ½ cup warm half-and-half, ½ teaspoon salt, and ¼ teaspoon white pepper. Keep covered on the lowest stovetop flame, stirring occasionally.

Serve Family Style

Spoon a cloud of mashed potatoes into a wide bowl, create a crater in the center, and ladle over a generous helping of beef tips and gravy. Shower with chopped parsley or chives for a pop of color and freshness. Offer crusty bread to swipe every last streak of gravy.

Expert Tips

Overnight Flavor Boost

Assemble everything the night before; cover and refrigerate the ceramic insert. In the morning, simply set it into the base and hit START. The extra marination time deepens flavor.

Starch Swap

No cornstarch? Use an equal amount of potato starch or ¼ cup all-purpose flour whisked with ⅓ cup water. Add gradually to avoid gluey clumps.

Wine Deglaze

For restaurant flair, deglaze your searing skillet with ½ cup dry red wine; scrape the browned bits and pour everything into the slow cooker. The tannins add complexity.

Veggie Bulk-Up

Stir in 2 cups frozen pearl onions or a handful of baby carrots during the last 2 hours for a complete one-pot meal.

Temperature Safety

If your slow cooker runs hot (many newer models do), check for tenderness at the 6-hour mark on LOW to prevent mushy meat.

Freezer Portions

Freeze cooled beef and gravy in silicone muffin trays; once solid, pop out and store in zip bags. Each “puck” is a perfect single-serve lunch portion.

Variations to Try

Mushroom Medley: Replace half the creminis with shiitake and oyster mushrooms for layered umami.
Gluten-Free Gravy: Swap the soy sauce for tamari and confirm your Worcestershire brand is gluten-free (Lea & Perrins original is in the U.S.).
Herbed Duchess Twist: Pipe the mashed potatoes into swirls, brush with egg wash, and broil 3 minutes for a golden crown.
Smoky Heat: Add ½ teaspoon chipotle powder and a diced chipotle in adobo to the broth for a gentle, smoky kick.
Low-Carb Serve: Spoon the beef tips over cauliflower mash or spaghetti-squash “hash” for a keto-friendly option.
French Onion Style: Caramelize the onions separately until chestnut-brown, then layer into the cooker for sweeter depth reminiscent of French onion soup.

Storage Tips

Cool leftovers completely within two hours. Transfer beef and gravy to airtight containers and refrigerate up to 4 days. For longer storage, place single servings in quart-size freezer bags, press out excess air, and freeze flat up to 3 months. Thaw overnight in the refrigerator, then reheat gently on the stovetop with a splash of broth to loosen the gravy. Mashed potatoes freeze best when piped into silicone muffin molds, frozen solid, then transferred to bags; reheat in a steamer basket for 6–8 minutes and whip briefly to restore fluffiness. If the gravy separates after thawing, whisk in 1 teaspoon cornstarch mixed with 2 teaspoons cold water while reheating; it will re-emulsify and regain its sheen.

Frequently Asked Questions

Yes. Stew meat is typically chuck, which contains more collagen and yields a slightly shreddier texture. Trim visible silver skin and cook the full 8 hours on LOW for best results.

Slow cookers trap moisture; even “low-sodium” broth can be watery. After stirring in the cornstarch slurry, prop the lid ajar for the final 20 minutes to allow evaporation, or add 1 tablespoon instant mashed-potato flakes for an all-natural thickener.

Absolutely. Use the sauté function to sear the beef, then pressure-cook on HIGH for 35 minutes with natural release for 10 minutes. Switch to SAUTÉ again to whisk in the cornstarch slurry until bubbly.

Slice them at least ¼-inch thick and add them raw; slow, moist heat keeps them supple. If you prefer a sautéed flavor, quick-sear mushrooms in butter first, then add during the last 2 hours so they don’t overcook.

Buttered egg noodles, cheese grits, or fluffy white rice soak up gravy beautifully. For low-carb, try cauliflower rice or roasted spaghetti squash tossed with Parmesan and herbs.

Yes, but keep the minimum liquid amount (1½ cups) so the slow cooker heats evenly. Cutting everything exactly in half works; cook time remains the same.
