Slow Cooker Pesto Parmesan Potatoes
Prep Time: 10 minutes | Cook Time: 4-5 hours on LOW or 2-2.5 hours on HIGH | Total Time: Approximately 4-5 hours
Yield: 6 servings
Ingredients
-
3 pounds baby gold or red potatoes, washed and quartered
-
1 cup prepared basil pesto (store-bought or homemade)
-
1 cup freshly grated Parmesan cheese, divided
-
2 tablespoons olive oil
-
Optional: 1 tablespoon chopped fresh basil or parsley, for garnish
-
Optional: ½ teaspoon kosher salt, to taste
-
Optional: ¼ teaspoon black pepper, to taste
-
Nonstick cooking spray or a little extra olive oil for greasing the slow cooker
Instructions
1. Prepare the Slow Cooker:
Lightly grease the inside of your slow cooker with nonstick cooking spray or a little olive oil so the potatoes and cheese do not stick too much.
2. Prepare the Potatoes:
Wash the baby potatoes well and pat them dry. Cut each potato into quarters so they cook evenly and soak up all the pesto flavor.
3. Coat the Potatoes:
In a large mixing bowl, combine the quartered potatoes, basil pesto, olive oil, and ½ cup of the grated Parmesan cheese. Toss until all the potatoes are well coated and glossy. If desired, season with a pinch of salt and black pepper, keeping in mind that pesto and Parmesan are already salty.
4. Transfer to Slow Cooker:
Transfer the coated potatoes to the prepared slow cooker, spreading them into an even layer so they cook at the same rate.
5. Cook:
Cover and cook on LOW for 4 to 5 hours, or on HIGH for about 2 to 2½ hours, until the potatoes are very tender when pierced with a fork. Gently stir once or twice during cooking to help the pesto and cheese redistribute, but do not worry if you cannot.
6. Add Remaining Cheese:
About 30 minutes before serving, sprinkle the remaining ½ cup of grated Parmesan evenly over the top of the potatoes. Cover again and continue cooking until the cheese is melted, lightly golden around the edges, and clinging to the potatoes.
7. Serve:
Once the potatoes are done, give them a gentle stir to mix the melted Parmesan throughout, being careful not to mash them. Taste and adjust seasoning with a little more salt and pepper if needed. Spoon the potatoes onto a serving plate. Garnish with chopped fresh basil or parsley for extra color and freshness if desired. Serve warm.
Recipe Notes & Pro Tips
Baby Potatoes: Baby gold or red potatoes (sometimes called creamer potatoes) have thin skins that do not need peeling. Their small size and waxy texture hold up well during slow cooking. If using larger potatoes, cut them into 1-inch chunks.
Pesto: Use your favorite store-bought or homemade basil pesto. Traditional pesto contains basil, garlic, pine nuts, Parmesan, and olive oil. If making your own, use high-quality ingredients. For a budget-friendly option, store-bought pesto works beautifully.
Parmesan Cheese: Freshly grated Parmesan provides the best flavor and melting texture. Pre-shredded Parmesan often contains anti-caking agents that can affect melting. Use a Microplane or fine grater for a light, fluffy cheese that melts quickly.
Do Not Overcook: The potatoes are done when they are fork-tender but still hold their shape. Overcooking can cause them to become mushy. Start checking at the lower end of the time range.
Add Protein (Optional): For a complete one-dish meal, add 1 pound of cooked Italian sausage (sliced) or 2 cups of shredded rotisserie chicken to the slow cooker along with the potatoes.
Make It Spicy: Add ½ teaspoon of red pepper flakes to the pesto mixture for a gentle kick of heat.
Variations
Garlic Pesto Potatoes: Add 4 cloves of minced fresh garlic to the pesto mixture. The garlic mellows during cooking and adds savory depth.
Lemon Pesto Potatoes: Add the zest of 1 lemon to the pesto mixture. The lemon adds brightness and cuts through the richness.
Sun-Dried Tomato Pesto Potatoes: Substitute basil pesto with sun-dried tomato pesto. The tomato pesto adds a sweet, tangy, umami flavor.
Spinach and Artichoke Pesto Potatoes: Add 2 cups of fresh spinach and 1 cup of chopped canned artichoke hearts to the slow cooker along with the potatoes. The spinach wilts and the artichokes add a tangy, creamy element.
Cheesy Pesto Potatoes: Increase the Parmesan to 1½ cups and add ½ cup of shredded mozzarella or provolone along with the final cheese. The extra cheese creates an even more golden, bubbly topping.
Herbed Pesto Potatoes: Add 1 tablespoon of fresh chopped rosemary, thyme, or oregano to the pesto mixture. The fresh herbs add an aromatic layer.
Serving Suggestions
These vibrant potatoes pair beautifully with:
-
Grilled chicken, steak, or pork chops
-
Roasted turkey or ham
-
Baked fish or salmon
-
Meatloaf or meatballs
For a complete meal, add:
-
Steamed green beans or broccoli
-
Roasted asparagus or Brussels sprouts
-
A simple green salad with a tangy vinaigrette
Garnish with fresh basil or parsley for a pop of color.
Storage & Reheating
Store leftovers in an airtight container in the refrigerator for up to 5 days.
To reheat, place individual portions in the microwave in 60-second bursts, or spread the potatoes on a baking sheet and warm in a 350°F oven for 8-10 minutes. The oven will help restore some crispness to the edges.
This dish does not freeze well, as the texture of the potatoes becomes mealy upon thawing.
Why This Recipe Works
This Pesto Parmesan Potato recipe is a brilliant example of how a few quality ingredients can create something extraordinary. The pesto provides a vibrant, herbaceous flavor that permeates the potatoes as they cook. The olive oil helps the pesto coat the potatoes evenly and adds richness. The Parmesan cheese adds a salty, nutty depth that complements the basil and garlic in the pesto.
The slow cooker is the perfect vessel for this dish because it allows the potatoes to cook gently, absorbing the pesto and cheese flavors without scorching or drying out. The low, even heat ensures the potatoes become tender while the Parmesan melts into a golden, bubbly topping.
This recipe is proof that you do not need a long list of ingredients or complicated techniques to make a memorable side dish. With four simple ingredients and a slow cooker, you can create pesto Parmesan potatoes that are vibrant, cheesy, and deeply satisfying. Perfect for holidays, potlucks, or any night you need an easy, crowd-pleasing side dish.
