This slow cooker 5-ingredient rosemary potatoes recipe is one of those dishes that quietly steals the show at family gatherings. My aunt has brought a version of this to every holiday and birthday party since I was a kid, and my mom still calls her for the recipe even though it’s ridiculously simple. The potatoes turn out tender with golden, crispy edges, and the combo of rosemary and garlic makes the whole house smell incredible for hours while they simmer away. It’s perfect for busy days when you want something comforting and homemade, but don’t have time to fuss with the oven.
These slow cooker rosemary potatoes are perfect alongside roast chicken, pork tenderloin, baked salmon, or even grilled sausages. I like to serve them straight from the slow cooker on warm so they stay hot during a potluck or family gathering. Add a big green salad or steamed green beans to round out the meal, and if you’re feeling a little extra, sprinkle the finished potatoes with freshly grated Parmesan or a squeeze of lemon juice for brightness right before serving.
Slow Cooker 5-Ingredient Rosemary PotatoesServings: 6
Ingredients
3 pounds small yellow or red potatoes, scrubbed and quartered
1/4 cup extra-virgin olive oil
4 cloves garlic, minced or thinly sliced
2 tablespoons fresh rosemary leaves, chopped
1 1/2 teaspoons kosher salt
Directions
Lightly grease the inside of a 4- to 6-quart slow cooker with a bit of olive oil or nonstick spray to help prevent sticking.
Add the quartered potatoes to the slow cooker, spreading them out as evenly as possible so they cook at the same rate.
In a small bowl, whisk together the olive oil, minced or sliced garlic, chopped fresh rosemary, and kosher salt until the garlic and herbs are evenly distributed in the oil.
Pour the rosemary-garlic oil over the potatoes. Use a large spoon or clean hands to toss the potatoes in the slow cooker until every piece is well coated and you can see rosemary and garlic clinging to the surfaces.
Cover the slow cooker with the lid and cook on HIGH for 3 to 4 hours, or on LOW for 5 to 6 hours, until the potatoes are very tender when pierced with a fork. Gently stir once or twice during cooking, if you’re home, to help the potatoes cook evenly and to bring some of the oil and garlic back over the top.
For crispier, lightly browned edges, remove the lid for the last 20 to 30 minutes of cooking on HIGH. Stir once more so some potatoes sit against the hot sides of the crock; they’ll develop golden, caramelized spots while still staying tender inside.
When the potatoes are done, give them a final gentle stir to redistribute the rosemary, garlic, and oil. Taste and add a pinch more salt if needed. Serve hot straight from the slow cooker, or transfer to a warm serving dish, spooning any garlicky rosemary oil from the bottom over the top.
Variations & Tips
If you don’t have fresh rosemary, you can use 2 teaspoons dried rosemary instead—crush it lightly between your fingers before adding to help release the flavor. For a little color and extra aroma, add a few grinds of black pepper or 1/2 teaspoon paprika along with the salt. If you like things cheesy, sprinkle 1/4 to 1/3 cup grated Parmesan over the potatoes during the last 10 minutes of cooking so it melts and clings to the crispy edges. To make this recipe feel more like a complete side, toss in thick-cut onion wedges on top of the potatoes before cooking; they’ll soften and sweeten in the rosemary oil. You can also swap part of the olive oil for melted butter for a richer flavor, keeping the total fat amount the same so the potatoes don’t get greasy. For meal prep, the potatoes can be scrubbed and cut the night before—store them submerged in cold water in the fridge, then drain and pat dry well before adding to the slow cooker so they roast instead of steam. Food safety tips: Keep the potatoes refrigerated (below 40°F/4°C) until you’re ready to cook, and don’t leave the finished dish at room temperature for more than 2 hours (or 1 hour if it’s a hot day or you’re outdoors). If you’re serving from the slow cooker at a gathering, keep it on the WARM setting so the potatoes stay above 140°F to avoid the temperature “danger zone.” Store leftovers in a shallow container in the fridge and use within 3 to 4 days; reheat thoroughly until steaming hot before eating.
