Let’s keep the Slow Cookin’ Summer Series going with this recipe from Bernadette from Rants From My Crazy Kitchen. Here’s her recipe:

Hi everyone! I’m Bernadette from Rants From My Crazy Kitchen, and I’m happy to join in the Slow Cookin’ Summer Series. I’m also a stay at home mom to a little girl that starts kindergarten today!

I just can’t get over how quickly that happened. On my blog I share a variety of recipes, from appetizers to desserts. I don’t have a lot of healthy recipes, but I sure have a lot with bacon! I just can’t get over how quickly that happened.

Today, however, I’m sharing a bacon-less favorite vegetable dish, made in the slow cooker instead of the traditional oven with this Broccoli Au Gratin.

Slow Cooker Broccoli Au Gratin

We joined a CSA (community supported agriculture) this summer, plus we have a large garden, which means we have a bunch of fresh vegetables in our house all summer long. I thought Broccoli Au Gratin would be a good way to use up some of the broccoli we have, and decided to try it in the slow cooker. I had never seen it made that way, and couldn’t find one recipe for it, so I may have invented something here! Making it in the slow cooker doesn’t cause the panko breadcrumb topping to become quite as crispy as baking a traditional au gratin does, but it still has some crispiness to it, and the broccoli is tender and cheesy. I will definitely be making this over and over! It would be a great side dish for Thanksgiving dinner, freeing up room in the oven for other things is always a plus.

  • 6 cups finely chopped broccoli
  • 2 cups light cream
  • 2 cups shredded mild cheddar cheese
  • 1 cup chicken broth
  • 1 cup panko breadcrumbs
  • ½ cup chopped yellow onion
  • ½ cup shredded aged Gouda cheese, or Parmesan cheese
  • 2 cloves garlic, minced
  • 4 tablespoons flour
  • 4 tablespoons butter, melted
  • ½ teaspoon salt
  • ¼ teaspoon ground nutmeg
  • teaspoon fresh ground black pepper
  • additional salt and pepper to season breadcrumbs


  • Chop all the vegetables and combine in a slow cooker. Add the chicken broth. Whisk together the light cream and flour with a fork, pressing the back of the fork against the measuring cup to break up the little crumbs of dry flour. Add cream/flour mixture to the broccoli mixture and stir. Add salt, nutmeg, and black pepper, stir again. Add cheeses and stir once more.
  • Combine the panko breadcrumbs and melted butter in a bowl, add salt and pepper to taste, mix well. Spoon the breadcrumb mixture over the top of the broccoli mixture.
  • Set the slow cooker to high and cook for 3-4 hours, or on low for 6-8 hours. Turn slow cooker off and allow to sit for about 10 minutes before transferring to a serving dish.
