Equipment You’ll Need for This Slow Cooker Beef and Potato Au Gratin

To make this beef and potato slow cooker comfort food, you’ll need the following tools:

• Slow cooker: I recommend a 6-quart slow cooker to ensure even cooking and enough space for layers. Look for one with a “High” setting to cook in 4 hours.
• Sharp knife and cutting board: For slicing the potatoes thinly and evenly (aim for 1/4-inch thickness).
• Skillet: You’ll need this to brown the ground beef before layering it in the cooker. A nonstick skillet will make cleanup much easier.
• Measuring cups and spoons: Accuracy is key for seasoning and liquid ratios.

If you’re shopping for a slow cooker, budget-friendly models with a timer function and “Keep Warm” setting are ideal for recipes like this.

Simple Ingredients for Slow Cooker Beef and Potato Au Gratin

This homemade cheesy beef potato dish comes together with pantry staples and fresh ingredients. Here are the key players:

• Potatoes: Russet potatoes work best because they hold their shape while becoming tender. You can substitute red or gold potatoes if needed, but make sure they’re sliced thinly.
• Ground beef: Lean ground beef brings savory depth to the dish. You can swap it for ground turkey or chicken for a lighter option.
• Cheese: Sharp cheddar adds rich, creamy flavor. For variety, try Swiss or Gruyère.
• Beef broth: Adds moisture and enhances the savory flavors. If unavailable, chicken broth works as a substitute.

Pro tip: Using pre-shredded cheese or pre-sliced potatoes can save even more prep time!

Slow Cooker Beef and Potato Au Gratin Ingredients

• 1 lb. ground beef, seasoned with a touch of salt and pepper
• 3 lbs. russet potatoes, peeled and sliced 1/4 inch thick (about 7 cups)
• 1 cup thinly sliced white onion
• 1 tsp. paprika
• 1/2 tsp. garlic powder
• 1 tsp. parsley
• 1 tsp. salt
• 1/4 tsp. pepper
• 3 cups shredded sharp cheddar cheese
• 1/2 cup beef broth (or chicken broth)

How to Make Slow Cooker Beef and Potato Au Gratin

1. Brown the ground beef in a skillet over medium heat, breaking it into crumbles as it cooks. Drain excess fat and season lightly with salt and pepper.
2. In a small bowl, mix the paprika, garlic powder, parsley, salt, and pepper.
3. Layer half of the potato slices in the bottom of your slow cooker.
4. Sprinkle over half of the sliced onions, half of the seasoning mixture, half of the cooked beef, and half of the cheese.
5. Repeat the layers with the remaining ingredients, finishing with the cheese as the top layer.
6. Drizzle the beef broth evenly over the layers.
7. Cover and cook on the “High” setting for 4 hours. Resist the urge to lift the lid during cooking, as this will slow down the process and result in firmer potatoes.
8. Once done, check that the potatoes are fork-tender and the cheese is fully melted. Serve immediately and enjoy!

Jake’s Tips for the Best Slow Cooker Beef and Potato Au Gratin

• Slice potatoes evenly: This ensures they cook at the same rate. A mandoline slicer is incredibly handy for this step.
• Pre-cook the beef: Browning the ground beef first enhances the flavor and avoids greasy results.
• Don’t open the lid: Every time you peek, you add cooking time. Trust your slow cooker to do its job.
• Layer carefully: Even layers help distribute the flavors, so don’t rush through this step.
• Reheat leftovers like a pro: Microwave individual portions or warm them in the oven at 350°F until heated through.

Easy Slow Cooker Beef and Potato Au Gratin Variations

• Use sweet potatoes: Swap russets for sweet potatoes for a slightly sweet and savory twist.
• Experiment with cheese: Try Swiss or pepper jack for a flavor change.
• Add veggies: Layer in spinach, mushrooms, or zucchini to sneak in more nutrients.
• Make it spicy: Add chopped jalapeños or red pepper flakes for a kick.

Slow Cooker Beef and Potato Au Gratin FAQs

Can I use other types of potatoes?

Yes! Red or gold potatoes work, but you’ll still want to slice them thinly for even cooking. Sweet potatoes are another great option.

Do I need to cook the beef beforehand?

Yes, browning the beef beforehand removes excess fat and enhances the overall flavor of the dish.

Can I use a smaller slow cooker?

A smaller slow cooker can work, but you may need to cut the recipe in half. Overcrowding could cause uneven cooking.

Swiss or Gruyère cheese are excellent options if you’re looking to switch things up. You can also mix and match cheeses for a custom blend.
