Easy Crockpot Buttery Onion Potatoes for a Simple Side Dish Tips, FAQ & printable recipe

Tips for success

For a more decadent finish, stir in a small amount of fresh chopped parsley or chives just before serving. These fresh herbs provide a bright, colorful contrast to the rich, savory flavors of the onion and butter.

If you prefer a slightly thicker sauce, you can remove the lid for the final 20 minutes of cooking to allow some of the excess liquid to evaporate, which will concentrate the flavors and create a more intense coating on the potatoes.

If you find that the potatoes are cooking faster than expected due to your specific slow cooker model, check them earlier than the recommended time. Slow cookers vary significantly in heat intensity, so getting to know how yours behaves is key to perfect results.

Always prioritize the texture of the potato over the clock; if they are fork-tender, they are ready, regardless of whether the minimum cooking time has passed.

Variations

• Cheesy Onion Potatoes: Stir in one cup of shredded cheddar cheese during the final ten minutes of cooking. The cheese melts into the buttery onion sauce, creating a rich and indulgent topping that pairs perfectly with the tender potatoes.
• Garlicky Herb Potatoes: Add two cloves of minced garlic and a teaspoon of dried thyme to the slow cooker during the assembly phase. These additions enhance the savory profile and provide an aromatic, earthy depth that complements the onion soup mix.

Storage and make-ahead

Fridge

Store in an airtight container in the refrigerator for up to 3 days.

Freezer

Freezing is not recommended as the potato texture may become grainy upon thawing.

Reheat

Reheat in a saucepan over medium heat or in the microwave until warmed through.

Allow any leftovers to cool to room temperature for no more than two hours before transferring them to an airtight container. Properly sealed, the potatoes can be stored in the refrigerator for up to three days.

When storing, try to keep some of the cooking juices with the potatoes to prevent them from drying out during the cooling and reheating process, which helps maintain their texture and flavor for later enjoyment.

These potatoes are excellent for making ahead as the flavors continue to develop while they rest in the refrigerator. You can prepare the dish entirely, let it cool, and store it for up to 48 hours before reheating.

When ready to serve, gently reheat them on the stovetop or in the microwave. This makes them a perfect side dish for meal prepping or for hosting, as they require very little attention once you are ready to eat.

Serving ideas

Serve these potatoes warm as a hearty side dish alongside roasted meats, grilled poultry, or a fresh green salad. The buttery onion profile complements a wide range of main courses, making it a versatile addition to your dinner menu. Because the sauce is savory and rich, it pairs particularly well with simpler, roasted proteins that allow the potatoes to stand out as a flavorful component of the meal.

For a casual serving style, keep the potatoes in the slow cooker on the 'warm' setting if your model has one, allowing guests to serve themselves. This keeps the dish at the perfect temperature throughout the meal. If serving plated, ensure that each portion includes a generous amount of the onion-flecked sauce from the bottom of the insert to maximize the flavor in every bite.

Easy Crockpot Buttery Onion Potatoes for a Simple Side Dish

Prep 5 minCook 4 hTotal 4 h 5 minServes 6

Ingredients

• 3 lb gold potatoes, quartered
• 1/2 cup butter, sliced
• 1 packet dry onion soup mix
• 1/2 cup vegetable broth

Instructions

1. Wash the gold potatoes thoroughly and cut them into uniform quarters, leaving the skins on for added texture and nutrients. Place the quartered potatoes into the ceramic insert of the slow cooker, stacking them evenly to ensure they cook at the same rate throughout the cooking cycle.
2. Distribute the butter slices over the top of the potato layer. Sprinkle the dry onion soup mix evenly over the potatoes and butter, ensuring the seasoning covers the surface. Pour the vegetable broth over the entire mixture to provide the liquid base needed for the potatoes to steam and braise properly during the slow cooking process.
3. Cover the slow cooker with its lid and cook on the low setting for 4 to 6 hours, or until the potatoes are fork-tender. Once cooked, gently toss the potatoes in the buttery onion juices that have collected at the bottom of the insert. Serve warm directly from the slow cooker.
