Slow Cooker Caramelized Onions

Posted by Kathy on June 2, 2015

caramelized onions

Stop! Do not push your slow cooker to the back of the cabinet just because summer is coming. Caramelized onions are one of my favorites, especially for summer cooking, and your trusty Crock Pot makes an easy-peasy big bunch.

What do I do with caramelized onions? Let me count the ways. Top grilled burgers. Grilled steaks. Grilled chops. Grilled pork tenderloin. Smoked brisket. Pizza and flat breads of all kinds. Sandwiches. Crostini. Dips. Quiche. Salad. Pasta salad. Vegetable tarts. Need I keep going?

Sure, you can make a batch in your skillet and use them in that dip or spoon them on top of the burger. But, that takes time and who wants to stand at the stove on a hot, summer day when everyone is outside grilling?

Crock Pot to the rescue. I make a big batch in the slow cooker. Then, freeze them in portion packs—maybe about ½ cup per freezer bag. Just thaw and use.

I grill most every night during the summer. (Well, truth be told, we grill all year long, and my wonderful hubby stands out in the rain and snow.) Spooning these caramelized onions over the grilled meats make them wonderful.  I often spoon them on grilled burgers. Last night we had a great sandwich. I grilled marinated pork cubes (on skewers) then served them with caramelized onions on hoagie rolls. We loved them.

So, get ready for summer cooking ahead.

Caramelized Onions

1 tablespoon olive oil
4 large sweet yellow onions, thinly sliced
2 tablespoons unsalted butter
Salt and pepper to taste

Pour oil into a 4 to 5-quart slow cooker. Brush the oil evenly over the stoneware. Add onions and dot with butter. Season with salt and pepper.

Cover and cook on High for 6 to 8 hours or until onions are caramelized. Stir once or twice while cooking.

Makes about 2 cups.

Tip: Spoon portions into freezer bags. Seal tightly. Label, date and freeze. To use, place in the refrigerator the night before to thaw or defrost in the microwave oven.
