Foil Packet Magic: Just 4 ingredients. My uncle makes these wrapped bundles for every late summer cookout and they stack up perfectly in the pot to keep everyone guessing what is inside.

These slow cooker 4-ingredient beef and black bean foil packets are a smart, low-effort way to turn a few pantry staples into a hearty meal with a bit of cookout nostalgia. Wrapping the filling in foil keeps each portion tidy and juicy while the slow cooker gently steams everything together, making this especially useful for casual gatherings, camping-style meals at home, or busy days when you want something filling without a long ingredient list.

Serve these packets with rice, warm tortillas, cornbread, or a crisp green salad to round out the meal. They also pair well with simple toppings set out on the table, such as sour cream, sliced avocado, salsa, shredded cheese, lime wedges, or extra cilantro, so everyone can open their packet and finish it to taste.

Slow Cooker 4-Ingredient Beef and Black Bean Foil Packets

Servings: 4

Ingredients

1 pound ground beef
1 packet taco seasoning, about 1 ounce
1 can black beans, 15 ounces, drained and rinsed
1 cup chunky salsa

Ground beef, black beans, taco seasoning, and salsa laid out for the recipe

Directions

1. Tear 4 large sheets of heavy-duty foil and set them on the counter. In a medium bowl, combine the ground beef, taco seasoning, black beans, and salsa until evenly mixed.

2. Divide the mixture evenly among the foil sheets, placing it in the center of each one. Fold the foil over and seal each packet tightly so the juices stay inside during cooking.

3. Arrange the packets in a single layer if possible, or stack them slightly in the slow cooker. Cover and cook on low for 4 to 5 hours or on high for 2 to 2 1/2 hours, until the beef is fully cooked.

4. Carefully open one packet to check doneness, then serve the packets hot straight from the foil or spoon the contents onto plates. Add chopped cilantro or your favorite toppings if desired.

Variations & Tips

Add a vegetable: Corn, diced bell pepper, or chopped onion can be mixed in with the beef for extra flavor and texture. If you add a fair amount of vegetables, keep the packets tightly sealed so the added moisture stays contained.

Use sturdier foil: Heavy-duty foil is best here because it is less likely to tear when lifting the packets in and out of the slow cooker. If standard foil is all you have, double-wrap each packet for insurance.

Make it spicier: Choose a hot salsa or stir in a pinch of crushed red pepper for a little more kick. This is an easy way to change the character of the dish without adding more major ingredients.

Serve taco-style: Instead of eating directly from the packet, spoon the cooked filling into tortillas or over tortilla chips. It turns the same simple mixture into a build-your-own dinner that works especially well for casual parties.
