These slow cooker 3-ingredient pesto baby potatoes are the kind of little kitchen trick my aunt would pull out every spring. She’d show up to family dinners with a crock full of these glossy, green, ridiculously flavorful bites and everyone assumed she’d been fussing for hours. In reality, it’s just tender baby potatoes, good basil pesto, and a sprinkle of Parmesan working together while you get on with your day. This is a simple, practical side dish that feels special enough for Easter or a Sunday roast, but easy enough for a busy weeknight.
Serve these pesto baby potatoes straight from the slow cooker on warm, or transfer them to a shallow bowl so that bright green pesto really shows off. They’re wonderful next to roasted or grilled chicken, pork chops, or a simple baked salmon. For a lighter meal, pair them with a big green salad or some roasted spring vegetables like asparagus or green beans. They also make a fun party side: set out toothpicks and let people spear the little potato halves right from the crock. A squeeze of fresh lemon and a few cherry tomatoes on the side brighten everything up.
Slow Cooker 3-Ingredient Pesto Baby Potatoes
Servings: 6
Ingredients
2 pounds baby gold potatoes, scrubbed and halved
1 cup prepared basil pesto (thick, refrigerated style preferred)
1/2 cup finely grated Parmesan cheese, plus extra for serving (optional)
Directions
Lightly grease the inside of a 4- to 6-quart slow cooker with a bit of oil or nonstick spray so the pesto doesn’t stick too much.
Place the halved baby potatoes into the slow cooker. If any potatoes are much larger than the others, cut them into quarters so they cook evenly and you get more of those bite-size pieces.
Spoon the basil pesto over the potatoes. Sprinkle the grated Parmesan cheese on top.
Using a spatula or large spoon, gently toss the potatoes right in the slow cooker until they are evenly coated in the pesto and Parmesan. Try to get as much pesto on the cut sides as you can—that’s what gives you that thick, vibrant green coating in the end.
Cover the slow cooker with the lid and cook on HIGH for 2 to 3 hours or on LOW for 4 to 5 hours, until the potatoes are very tender when pierced with a fork. Try not to lift the lid too often, as that releases heat and can slow down cooking.
Once the potatoes are tender, give everything a gentle stir so any pesto and cheese from the bottom gets scooped up and coats the potatoes again. They should look glossy, with a thick, bright green pesto layer clinging to the golden potato halves.
Taste one potato and add a pinch of salt if needed, keeping in mind that both pesto and Parmesan are already salty. If you’d like, sprinkle a little extra Parmesan over the top for a final cheesy finish.
Serve the potatoes straight from the slow cooker on the WARM setting, or transfer to a serving dish. Spoon any extra pesto from the bottom of the crock over the top so every bite is packed with flavor.
Variations & Tips
For picky eaters, you can stir in a small handful of shredded mozzarella or mild cheddar right at the end to make the potatoes extra cheesy and a little more familiar. If your kids are sensitive to strong flavors, start with 3/4 cup pesto instead of a full cup, taste at the end, and add a bit more if everyone’s on board. You can also use a nut-free pesto if there are allergies in the house—many store-bought versions contain pine nuts or other tree nuts, so always read the label carefully. If you prefer a lighter flavor, stir in a squeeze of fresh lemon juice just before serving to brighten the dish without adding more ingredients to the slow cooker itself. For a slightly different twist, swap in red or purple baby potatoes, or use a mix for a colorful bowl. To turn this into a more substantial meal, toss in some pre-cooked chicken sausage slices during the last 30 minutes of cooking so they warm through in the pesto. Food safety tips: Make sure to scrub the potatoes well under running water to remove any dirt before cooking. Keep the slow cooker covered during cooking so the potatoes reach and maintain a safe temperature. Once cooked, do not leave the potatoes sitting at room temperature for more than 2 hours; switch the slow cooker to WARM if you’re serving over time, and refrigerate leftovers in a shallow container within 2 hours. Reheat leftovers thoroughly until steaming hot before serving.
