• ½ cup breadcrumbs or panko

• 1 packet onion soup mix (or see homemade version below)

• 1 egg

• 2 tbsp Worcestershire sauce

• 1 tsp garlic powder

• ½ tsp black pepper

• ½ tsp salt (optional—soup mix is salty)

Mushroom Gravy

• 2 cups sliced mushrooms (white or cremini)

• 1 medium onion, sliced (optional but recommended)

• 2 cups beef broth

• 2 tbsp Worcestershire sauce

• 1 tbsp soy sauce (adds depth)

• 1 tsp garlic powder

• ½ tsp onion powder

• ½ tsp paprika

• ¼ tsp black pepper

🔪 Instructions

1️⃣ Make the Patties

1. In a large bowl, combine:

   • Ground beef

   • Breadcrumbs

   • Onion soup mix

   • Egg

   • Worcestershire

   • Garlic powder & pepper

2. Mix gently (don’t overwork or patties get tough).

3. Form into 4–6 oval patties, about ¾-inch thick.

2️⃣ Optional but Recommended: Brown the Patties

This adds flavor but can be skipped if you’re short on time.

• Heat a skillet over medium-high with a little oil.

• Sear patties 1–2 minutes per side until browned (not cooked through).

• Transfer to slow cooker.

3️⃣ Layer the Slow Cooker

• Place mushrooms and onions in the bottom of the crockpot.

• Lay patties on top.

• Sprinkle extra mushrooms over the patties (like in the image).

4️⃣ Make the Gravy

In a bowl, whisk together:

• Beef broth

• Worcestershire sauce

• Soy sauce

• Garlic powder

• Onion powder

• Paprika

• Black pepper

Pour evenly over patties.

5️⃣ Slow Cook

• LOW: 6–8 hours

• HIGH: 3–4 hours

Patties will be ultra-tender and swimming in gravy.

6️⃣ Thicken the Gravy

1. Mix cornstarch + cold water.

2. Stir into slow cooker.

3. Cover and cook 15–20 minutes on HIGH, until thickened.

🍽️ Serve With

• Mashed potatoes 🥔 (classic)

• Egg noodles

• Rice

• Buttered green beans or peas

Spoon lots of gravy over everything.

✨ Pro Tips

• Don’t stack patties too tightly—overlapping is fine.

• For richer gravy, stir in 2 tbsp sour cream at the end.

• Ground turkey works, but add 1–2 tbsp olive oil for moisture.

• Leftovers are even better the next day.

🧅 Homemade Onion Soup Mix (Optional)

If skipping the packet:

• 3 tbsp dried minced onion

• 1 tsp onion powder

• ½ tsp garlic powder

• ½ tsp sugar

• ½ tsp salt

• ¼ tsp black pepper
