Ingredients

• 2½ pounds baby potatoes, halved
• 6 tablespoons unsalted butter, melted
• 1 packet dry onion soup mix
• ½ cup chicken broth
• ½ teaspoon black pepper
• 2 tablespoons chopped fresh parsley, optional for serving

How to Make Slow Cooker Onion Butter Potatoes

1. Prepare the Potatoes

Wash the baby potatoes thoroughly and cut them in half. If some potatoes are larger than others, cut them into similar-sized pieces so they cook evenly.

Place the potatoes directly into the slow cooker.

2. Add the Onion Butter

Melt the butter and pour it over the potatoes.

Sprinkle the dry onion soup mix and black pepper over everything. Pour in the chicken broth and gently toss the potatoes until they are evenly coated.

3. Slow Cook

Cover the slow cooker and cook on LOW for 4–5 hours or on HIGH for 2½–3½ hours, until the potatoes are fork-tender.

Cooking times can vary depending on the size of the potatoes and your slow cooker.

4. Stir and Finish

Once the potatoes are tender, gently stir them in the buttery onion sauce.

If desired, sprinkle with fresh parsley just before serving for a little color and freshness.

5. Serve

Transfer the potatoes to a serving bowl and spoon some of the onion-butter sauce over the top.

Serve them hot alongside your favorite main course.

Tips for the Best Onion Butter Potatoes

Use baby potatoes when possible. Their small size makes them ideal for slow cooking and gives the finished dish a tender, creamy texture.

Cut potatoes evenly. Similar-sized pieces will cook at approximately the same rate.

Don’t add too much liquid. Potatoes release moisture as they cook, so a modest amount of broth is enough to create a flavorful buttery sauce.

Keep the lid closed. Opening the slow cooker frequently lets heat escape and can extend the cooking time.

Easy Variations

For a richer flavor, use Yukon Gold potatoes instead of baby potatoes.

You can add shredded cheddar during the final 15–20 minutes for cheesy onion potatoes.

For a fresh finish, sprinkle the cooked potatoes with chopped parsley or green onions before serving. These additions are optional and do not affect the core recipe.

What to Serve With Onion Butter Potatoes

These potatoes pair beautifully with almost any hearty main course. Serve them alongside roast chicken, pork chops, meatloaf, pot roast, baked ham, steak, or roasted turkey.

They are also a wonderful addition to holiday dinners and family-style meals.

How to Store Leftovers

Allow leftover potatoes to cool before transferring them to an airtight container.

Refrigerate for up to 3–4 days.

Reheat gently in the microwave or in a covered skillet over low heat. Add a small splash of broth if the potatoes seem dry.

Frequently Asked Questions

Can I use russet potatoes?

Yes. Russet potatoes can be used, although they are softer and more starchy than baby or Yukon Gold potatoes.

Can I use salted butter?

Yes. If using salted butter, you may want to choose a lower-sodium onion soup mix or avoid adding additional salt.

Can I make these potatoes ahead of time?

Yes. Cook them completely, refrigerate them, and reheat gently before serving. Add a small splash of broth or melted butter if needed.

Can I make them cheesy?

Absolutely. Sprinkle shredded cheddar or another melting cheese over the potatoes during the final 15–20 minutes of cooking and cover until melted.
