These 5-ingredient slow cooker Cinco de Mayo potatoes are the kind of set-it-and-forget-it dish that makes feeding a crowd feel easy. Raw peeled cubed russet potatoes go straight into the slow cooker with just four simple additions—no pre-cooking, no fuss—and come out tender, creamy, and full of zesty Mexican-inspired flavor. It’s a fun, budget-friendly way to bring a little fiesta flair to your table, whether you’re celebrating Cinco de Mayo or just need a reliable side that everyone will be begging you to make again.
Serve these potatoes hot right from the slow cooker, sprinkled with a little extra shredded cheese and fresh cilantro if you like. They pair beautifully with tacos, grilled chicken, fajitas, or simple baked fish. Add a side of salsa, guacamole, and a crisp green salad or corn on the cob to round out the meal. They also work as a hearty brunch side alongside scrambled eggs or breakfast burritos.
5-Ingredient Slow Cooker Cinco de Mayo PotatoesServings: 6
Ingredients
3 pounds russet potatoes, peeled and cut into 1-inch cubes
1 (1-ounce) packet taco seasoning (mild or medium)
1 cup jarred salsa (red or green, your choice)
1 cup shredded Mexican blend cheese, divided
2 tablespoons olive oil or melted butter
Optional: 1 teaspoon salt, to taste (if your taco seasoning is low-sodium)
Directions
Lightly grease the inside of your slow cooker with a little oil or nonstick spray to help prevent sticking.
Place the raw peeled cubed russet potatoes in an even layer on the bottom of the slow cooker. This should look like a full, even bed of fresh potato cubes waiting to cook.
Drizzle the olive oil or melted butter over the potatoes and gently toss with a large spoon or clean hands right in the slow cooker to lightly coat the cubes.
Sprinkle the taco seasoning evenly over the potatoes. If your taco seasoning is low-sodium and you like a saltier dish, add the optional salt now. Toss again until the potatoes are well coated and speckled with seasoning.
Pour the salsa evenly over the seasoned potatoes. Do not stir too aggressively; just gently fold once or twice so some salsa seeps down between the cubes while still mostly resting on top.
Sprinkle half of the shredded Mexican blend cheese (1/2 cup) evenly over the top of the potatoes and salsa.
Cover the slow cooker with the lid and cook on HIGH for 3 to 4 hours or on LOW for 6 to 7 hours, until the potatoes are very tender when pierced with a fork. Avoid lifting the lid too often so the heat and moisture stay inside.
Once the potatoes are tender, gently stir everything together to coat the cubes in the cheesy, saucy mixture. Taste and adjust seasoning with a bit more salt if needed.
Sprinkle the remaining 1/2 cup shredded cheese over the top, cover, and let sit on WARM or LOW for about 5 to 10 minutes, just until the cheese is melted and gooey.
Serve the potatoes straight from the slow cooker, giving them a gentle stir to scoop up plenty of sauce and cheese with each serving.
Variations & Tips
For picky eaters, use mild taco seasoning and a mild, smooth salsa (without big chunks of peppers or onions). You can even stir in a few tablespoons of sour cream at the end for an extra creamy, less spicy version. For extra veggies, add 1 cup of frozen corn or a drained can of black beans on top of the potatoes before cooking; they’ll warm and soften right along with the potatoes. If you prefer a more loaded-bake style, top finished potatoes with sliced green onions, chopped tomatoes, or a dollop of Greek yogurt or sour cream. To keep this dairy-free, skip the cheese and use a dairy-free shredded cheese alternative or simply serve the seasoned potatoes with salsa and avocado on the side. For a crispier texture, you can spread the finished potatoes on a sheet pan and broil for a few minutes to brown the tops. Food safety tips: Cut potatoes into evenly sized cubes (about 1 inch) so they cook through at the same rate; very large chunks may stay underdone in the center. Make sure the potatoes are fully tender and steaming hot in the middle before serving. Keep the slow cooker covered during cooking to maintain a safe, steady temperature. Do not leave cooked potatoes sitting at room temperature for more than 2 hours; refrigerate leftovers promptly in a shallow container and use within 3 to 4 days, reheating until piping hot before serving.
