Why You Will Love This Crockpot Recipe

Pierogi are usually:

  • boiled,
  • then pan fried in butter.

But the slow cooker changes everything.

The pierogi slowly soak in broth, becoming tender and silky without breaking apart.

Butter melts over them, turning the cooking liquid into a creamy sauce.

By the time you lift the lid, every pierogi tastes like it was drenched in buttery gravy.

It’s comfort food in the easiest form.

Prepare the Crockpot Layers

Step 1 — Add Pierogi

Place frozen pierogi directly into the slow cooker.

No need to thaw—they hold their shape better straight from the freezer.

Step 2 — Add Onion and Butter

Sprinkle sliced onions across the pierogi.

Scatter cubes of butter evenly over the top (like in your picture).

This creates that classic Polish buttery flavor.

Add Broth and Cook

Step 3 — Pour the Broth

Add chicken broth over the pierogi until they are mostly covered.

Don’t worry if some edges stick up—the steam cooks everything.

Season lightly with salt and pepper.

Step 4 — Slow Cook

Cover and cook:

  • Low for 4 hours
    OR
  • High for 2 to 2½ hours

Check once halfway, gently stirring to make sure pierogi are evenly cooking and not sticking.

Add Cheese and Sour Cream

Step 5 — Stir in Creaminess

When pierogi are tender and broth has mostly reduced:

  • add cheddar cheese
  • stir in sour cream
  • taste and re-season

Let cook 15 more minutes to melt and thicken into a sauce.

Serve and Enjoy

Step 6 — Dish Up

Scoop buttery cheesy pierogi into bowls.

Top with:

  • more cheese
  • bacon bits
  • crispy onions
  • fresh herbs
  • sour cream dollops

It’s a meal you’ll crave again before you finish your first serving.

Tips for Perfect Crockpot Pierogi

Don’t Overcook

Too long and pierogi may split open.

Stick to the time listed.

Use a Wide Slow Cooker

Layers cook more evenly when pierogi aren’t piled too deep.

Cheese Choice

Cheddar melts creamy, but Colby Jack or mozzarella work too.

Add Flavor Boost

Sauté onions and garlic before adding for richer flavor.

Optional Flavor Variations

Bacon & Onion Pierogi

Add ½ cup cooked chopped bacon + a splash of broth reserved from the pan.

Creamy Mushroom

Sauté mushrooms in butter, toss in + add an extra spoon sour cream.

Buffalo Style

Stir in ¼ cup buffalo sauce + blue cheese crumbles to serve.

Polish Classic

Skip cheese; top with butter-browned onions only.

Serving Ideas

  • Serve with grilled sausages
  • Add as a side to roasted chicken
  • Pair with a crunchy green salad
  • Put leftovers in a skillet the next day to crisp up!

Storing Leftovers

Fridge

Up to 3 days in airtight container

Freezer

Not recommended once cooked — pierogi get mushy

Reheat

Microwave gently OR heat in skillet with a splash of broth or butter
