These 4-ingredient slow cooker Cinco de Mayo week potatoes are the kind of easy, family-friendly side dish that makes busy weeknights feel a little more festive. You literally dump raw whole unpeeled purple potatoes into the crock, add three simple ingredients, and let the slow cooker do the work while you handle everything else. The purple potatoes bring a fun pop of color that kids love, and the mild, zesty flavors nod to Cinco de Mayo without being too spicy for picky eaters. This is the kind of recipe that has husbands wandering back to the kitchen for seconds—and usually thirds.
Serve these tender, garlicky, lime-kissed purple potatoes alongside tacos, fajitas, burrito bowls, or grilled chicken for an easy Cinco de Mayo spread. They’re also great with simple baked fish or pork chops when you want a colorful, no-fuss side. Add a bowl of salsa, guacamole, and a simple green salad or corn salad to round out the meal. If you’re feeding a crowd, keep the slow cooker on warm and let everyone scoop potatoes straight from the crock as they build their plates.
4-Ingredient Slow Cooker Cinco de Mayo Purple PotatoesServings: 6
Ingredients
2 pounds small whole purple potatoes, unpeeled and well-scrubbed
3 tablespoons salted butter, cut into small pieces
1 packet (about 1 ounce) mild taco seasoning mix
2 tablespoons fresh lime juice (from about 1–2 limes)
Directions
Rinse the whole purple potatoes well under cool running water, scrubbing gently with a brush or your hands to remove any dirt. Leave the skins on and pat them dry with a clean towel.
Lightly spray the inside of your slow cooker with nonstick cooking spray or rub it with a little butter or oil to help with cleanup.
Dump the raw whole unpeeled purple potatoes into the bottom of the slow cooker, spreading them into an even layer so they cook as evenly as possible.
Sprinkle the taco seasoning packet evenly over the potatoes. Use your hands or a spoon to gently toss the potatoes so they’re lightly coated in the seasoning.
Dot the top of the seasoned potatoes with the pieces of butter, spacing them around so they melt and drip down over the potatoes as they cook.
Cover the slow cooker with the lid and cook on HIGH for 3–4 hours or on LOW for 6–7 hours, or until the potatoes are very tender when pierced with a fork. Cooking time can vary depending on the size of your potatoes and your specific slow cooker.
Once the potatoes are tender, pour the fresh lime juice over them. Use a large spoon to gently toss the potatoes in the buttery, seasoned juices at the bottom of the crock so everything gets coated and glossy.
Taste a potato and add a small pinch of salt if needed (this will depend on how salty your taco seasoning and butter are). If you’d like a bit more brightness, you can squeeze in an extra teaspoon or two of lime juice.
Serve the potatoes straight from the slow cooker, spooning some of the buttery, taco-lime sauce over the top of each portion. Keep the slow cooker on the WARM setting if people will be coming back for seconds and thirds.
Variations & Tips
For picky eaters, choose a very mild taco seasoning or use half a packet the first time you make it; you can always sprinkle a little extra on individual servings. If your family prefers less tang, reduce the lime juice to 1 tablespoon or serve lime wedges on the side so everyone can squeeze their own. To make it a bit richer, stir in 1/4 cup sour cream or Mexican crema right before serving for a creamy coating. For a little extra color and flavor, you can toss in 1/2 cup shredded cheddar or pepper jack cheese during the last 15 minutes of cooking and let it melt over the potatoes. If you don’t have salted butter, use unsalted and add an extra pinch of salt at the end. You can also swap the taco seasoning for fajita seasoning or a homemade blend of chili powder, cumin, garlic powder, onion powder, and salt. Food safety tips: Always scrub the potatoes well before cooking to remove dirt, and cut away any large green spots or deep eyes before placing them in the slow cooker. Use a slow cooker that is at least half full but not more than about two-thirds full so the potatoes heat evenly and reach a safe temperature. Keep the lid on while cooking to maintain proper heat, and check that the potatoes are very tender all the way through (a fork should slide in easily) before serving. Refrigerate leftovers within 2 hours of cooking in a shallow container, and reheat thoroughly until steaming hot before eating.
