Spread cheap peanut butter over raw ground beef tube, together with 2 ingredients, into slow cooker for a budget supper that disappears faster than anything else

This ultra-budget slow cooker loaf leans into old-fashioned pantry cooking, the kind of practical meal that stretches simple ingredients into something filling for a long weekend supper. While the original concept is very bare-bones, this version turns ground beef, peanut butter, oats, and ketchup into a sliceable savory loaf with a surprisingly hearty texture and a sweet-salty glaze that makes it feel more complete than the ingredient list suggests.

Serve thick slices with mashed potatoes, buttered green beans, corn, or simple roasted carrots for an affordable Labor Day plate. It also works well with white bread, a scoop of coleslaw, or baked beans if you want a backyard-cookout feel without turning on the grill.

Servings: 6

Ingredients

2 pounds ground beef, formed as a loaf
1/2 cup inexpensive creamy peanut butter
1 cup old-fashioned oats
3/4 cup ketchup

Ground beef, peanut butter, oats, and ketchup on a countertop

Directions

1. Lightly coat the inside of the slow cooker with nonstick spray or line it with a wide strip of parchment for easier lifting. Shape the ground beef into an even oval loaf that fits inside the cooker.

2. Spread the peanut butter all over the top and sides of the raw beef loaf in a thin, even layer.

3. Press the oats gently over the peanut butter so they stick to the outside of the loaf, covering the top and sides as evenly as possible.

4. Spoon the ketchup over the top, spreading it into a simple glaze. Cover and cook on low for 4 to 5 hours, or until the loaf is cooked through and reaches a safe internal temperature of 160 degrees Fahrenheit.

5. Carefully lift out the finished loaf or use two spatulas to transfer it to a plate. Let it rest for 10 minutes before slicing so it holds together better.

6. Slice and serve warm with your favorite budget-friendly sides.

Variations & Tips

For better texture: If you have one extra pantry staple to spare, mix 1 beaten egg into the beef before shaping the loaf. It helps the slices hold together more neatly after slow cooking.

Make it sweeter: Stir 1 to 2 tablespoons brown sugar into the ketchup before spreading it on top if your family likes a more classic sweet meatloaf-style finish.

Use a leaner beef: Ground beef around 85 to 90 percent lean will give you less grease in the slow cooker. If you use fattier beef, carefully drain off the excess liquid before resting and slicing.

Meal prep tip: This loaf reheats surprisingly well. Store slices in the fridge for up to 3 days and warm them in a skillet or microwave for quick lunches with leftover potatoes or a sandwich on toast.
