Introduction

Slow Cooker Salisbury Steak is pure comfort food—the kind that feels like a diner classic, but made easy at home. You get juicy beef patties that simmer gently in a savory onion gravy until they’re tender, flavorful, and perfect for spooning over mashed potatoes, rice, or egg noodles.

This version is ideal for busy days because the slow cooker does the heavy lifting. A quick pan-sear adds that “made-from-scratch” flavor (and helps the patties hold together), then everything finishes low and slow in a creamy, beefy gravy. It’s a cozy, budget-friendly dinner that feeds a crowd and reheats beautifully—so it’s great for meal prep, too.

If you love meals that taste like they took all day (but didn’t), this is one you’ll make on repeat.

Equipment

• 4-qt slow cooker (or larger)
• Large mixing bowl
• Measuring cups and spoons
• Large skillet
• Tongs or spatula
• Shallow dish or plate (for flour dredging)
• Whisk
• Spoon or ladle

Ingredients

Main Ingredients

• 2 lb 90% lean ground beef
• 1 (1-oz) packet dry onion soup mix
• 1/2 cup Italian-seasoned bread crumbs
• 1/4 cup milk
• 1/4 cup all-purpose flour (for dredging)
• 2 Tbsp vegetable oil

Gravy / Sauce Ingredients

• 2 (10.75-oz) cans condensed cream of chicken soup
• 3/4 cup water
• 1 (1-oz) packet dry au jus mix

Optional Ingredients

• Cracked black pepper (for serving)
• Fresh chopped parsley (for serving)
• Sautéed mushrooms or sliced onions (stir into gravy if you want)
• Mashed potatoes, egg noodles, or rice (for serving)

Instructions

Step 1: Preparation

1. Lightly grease the slow cooker insert (optional, but helps with cleanup).

2. In a large bowl, combine the ground beef, dry onion soup mix, bread crumbs, and milk. Mix gently with clean hands just until combined—don’t overwork it (that can make patties tough).

3. Shape the mixture into 8 even patties.

4. Spread the flour on a plate and lightly dredge each patty in flour, shaking off excess.

Step 2: Mixing / Assembling

1. In a medium bowl, whisk together the cream of chicken soup, water, and au jus mix until smooth.

2. Add a thin layer of gravy to the bottom of the slow cooker (just a few spoonfuls helps prevent sticking).

3. Place half the browned patties in the slow cooker, then spoon about half the gravy mixture over them. You’ll repeat with the remaining patties and gravy after browning.

Step 3: Cooking / Baking

1. Heat vegetable oil in a large skillet over medium-high heat.

2. Working in batches, sear patties for about 5 minutes total, turning once halfway through, until browned on both sides. They don’t need to cook through—just get color.

3. Transfer the browned patties into the slow cooker in layers, pouring gravy over each layer.

4. Cover and cook:

   • Low: 4 to 5 hours

   • High: 2 to 2 1/2 hours
     Cook until patties are tender and reach 165°F in the center.

Step 4: Resting / Finishing

1. If the gravy looks a bit oily, skim off excess fat with a spoon before serving.

2. Taste the gravy and add cracked black pepper if you like. (It’s usually salty enough because of the mixes.)

3. Sprinkle with parsley for a fresh finish.

4. Serve hot over mashed potatoes, rice, or noodles.

Tips & Notes

• Tip for tender patties: Mix the meat gently and stop as soon as everything is combined. Overmixing can make patties dense.
• Tip for richer flavor: Don’t skip browning—those browned bits add a deep, savory taste.
• Common mistake to avoid: Packing patties too tightly can make them tough. Shape them lightly.
• If gravy is too thick: Stir in a splash of warm water or broth near the end.
• If gravy is too thin: Mix 1 Tbsp cornstarch with 1 Tbsp cold water and stir in during the last 15–20 minutes on High (or 30 minutes on Low).
• Want more “from-scratch” vibes? Add sautéed mushrooms and onions into the slow cooker before cooking.

Variations

Ingredient Variations

• Mushroom gravy upgrade: Add 8 oz sliced mushrooms (sauté first for best flavor).
• Onion lovers: Add 1 sliced onion to the slow cooker for more texture and sweetness.
• More savory depth: Add 1 tsp Worcestershire sauce to the gravy mix.
• Spicy twist: Add a pinch of cayenne or smoked paprika to the patties.

Dietary Variations

• Gluten-free: Use gluten-free bread crumbs and a gluten-free flour blend for dredging. Confirm your soup and mixes are gluten-free.
• Dairy-free: Use unsweetened dairy-free milk and dairy-free condensed soup alternative (results vary by brand).

Frequently Asked Questions

Can I use leftovers or substitutions?

Yes. Leftovers are great over toast, rice, or noodles. You can swap 90% lean beef for 85% lean (you may want to skim more fat). You can also use plain bread crumbs and add a pinch of Italian seasoning.

Can I make this recipe ahead of time?

Definitely. Shape the patties the day before and refrigerate. You can also fully cook the dish, cool, and reheat when ready to serve—flavors get even better.

How do I reheat it properly?

Reheat gently on the stovetop over medium-low heat, adding a splash of water if needed. Or microwave in short bursts, stirring the gravy between rounds.

Can I freeze this recipe?

Yes. Freeze patties in gravy for best moisture. Thaw overnight in the fridge and reheat slowly until hot.
