Some nights you want a warm, filling dinner without standing over the stove for an hour. These slow cooker beef patties with onion gravy fit that need. Seasoned ground beef patties simmer in a rich, savory onion gravy until tender, and the sauce thickens into something you will want to spoon over mashed potatoes or rice.
Why You’ll Love This Recipe

- Simple ingredients: You need ground beef, onions, beef broth, and a few pantry seasonings.
- Rich, savory gravy: Slowly cooked onions build a deep flavor that makes the sauce taste like it simmered all day.
- Easy to serve: Pair it with mashed potatoes, egg noodles, or steamed rice for a complete meal.
Ingredients
- 1 lb (450 g) ground beef, 80/20 blend
- 1/2 tsp salt, plus more to taste
- 1/4 tsp black pepper
- 1/2 tsp garlic powder
- 1/2 tsp onion powder
- 1 tbsp (15 ml) vegetable oil
- 1 large yellow onion, thinly sliced (about 2 cups / 300 g)
- 1 1/2 cups (360 ml) beef broth
- 1 tbsp (15 ml) Worcestershire sauce
- 2 tbsp (16 g) all-purpose flour, or 1 1/2 tbsp cornstarch mixed with 3 tbsp (45 ml) cold water
Ingredient Notes
An 80/20 ground beef keeps the patties juicy during slow cooking. Leaner beef can work, but the patties may turn out drier. Worcestershire sauce adds depth to the gravy, and you can leave it out if needed. Flour or cornstarch thickens the gravy. Cornstarch gives a glossier finish and is a good gluten-free option.
Equipment You’ll Need
- Slow cooker (4 to 6 quart)
- Large skillet
- Mixing bowl
- Spatula
- Instant-read food thermometer
How to Make Slow Cooker Beef Patties with Onion Gravy
- Season the beef. In a bowl, combine the ground beef, salt, pepper, garlic powder, and onion powder. Mix gently with your hands until just combined, then shape into 4 patties about 3/4 inch (2 cm) thick. Overmixing makes the patties dense.
- Brown the patties. Heat the oil in a large skillet over medium-high heat. Cook the patties for about 2 to 3 minutes per side, until deep brown on the outside. They do not need to be cooked through. Browning adds flavor, and it is worth the extra few minutes.
- Layer the slow cooker. Spread the sliced onions across the bottom of the slow cooker. Place the browned patties on top of the onions.
- Make the gravy base. In a bowl, whisk the beef broth and Worcestershire sauce. Pour the mixture over the patties and onions.
- Cook low and slow. Cover and cook on low for about 4 to 6 hours, or on high for about 2 to 3 hours. These times are estimates, since slow cookers vary. The patties are done when the internal temperature reaches 160°F (71°C) and the onions are very soft.
- Thicken the gravy. Remove the patties to a plate. If using flour, whisk it into 1/4 cup (60 ml) of the hot cooking liquid until smooth, then stir it back into the slow cooker. If using cornstarch, stir the cornstarch slurry into the liquid. Switch the slow cooker to high, uncovered, and cook 10 to 15 minutes, until the gravy thickens enough to coat a spoon.
- Serve. Return the patties to the gravy, spoon the onions over the top, and taste for salt and pepper before serving.
Pro Tips for the Best Results
- Brown the patties before adding them to the slow cooker. This creates flavor that the slow cooking alone cannot provide.
- Slice the onions evenly so they soften at the same rate.
- Check the seasoning at the end, since broth brands vary in saltiness.
- Use a food thermometer instead of guessing when the patties are done.
- Let the gravy sit for a few minutes after thickening, so it sets to a silkier texture.
Common Mistakes to Avoid
Gravy that is too thin: Make sure the thickener is fully whisked in and the gravy comes to a simmer after adding it. Patties that fall apart: Handle the meat gently and avoid overworking it. Bland gravy: Brown the onions and patties well and season the broth to taste at the end. Overcooked patties: Check the internal temperature earlier in the cook time if your slow cooker runs hot.
Variations and Substitutions
- Mushroom gravy: Add 8 oz (225 g) of sliced mushrooms with the onions.
- Cheesy version: Top each patty with a slice of cheddar during the last 10 minutes of cooking.
- Ground turkey: Use lean ground turkey and add a little extra oil, since it is less fatty than beef.
- Herb boost: Stir in fresh thyme or parsley just before serving.
Serving Suggestions
Serve the patties over creamy mashed potatoes so they soak up the gravy. Egg noodles, white rice, or buttered green beans also pair well. A simple green salad balances the richness of the meal.
Storage and Reheating
Refrigerate leftovers in an airtight container within 2 hours of cooking. Eat within 3 to 4 days. To freeze, cool completely, portion into freezer-safe containers, and use within 2 to 3 months. Reheat in a saucepan over medium heat, adding a splash of broth if the gravy has thickened too much, until the patties are hot throughout.
Frequently Asked Questions
Can I make these patties ahead of time?
Yes. You can shape the patties a day ahead and keep them refrigerated on a plate covered with plastic wrap. Brown and cook them the day you plan to serve.
Can I freeze slow cooker beef patties?
Yes, you can freeze them with the gravy. Let them cool first, then store in an airtight container for up to 2 to 3 months.
Why are my patties dry?
Lean beef, overcooking, or overmixing the meat are the most common causes. Use 80/20 beef and check the internal temperature.
How do I know when the patties are done?
Use an instant-read thermometer. Ground beef is safe at 160°F (71°C) internal temperature.
Can I skip browning the patties?
You can, but the flavor will be milder and the patties will look pale. Browning takes only a few minutes and makes a noticeable difference.
