The Story Behind Our Easy Gluten Free Hash Brown Casserole

My mother-in-law passed away a few years ago, but she and I shared a love of cooking and cookbooks. She told me a few weeks before she went to be with the Lord that she was really excited about the cookbook I was writing at the time and hoped to be able to see it. Sadly, she did not. However, before she died, she gave me something I will always treasure–all of her recipes in one hand-typed cookbook.

Family cookbook

One of those treasured recipes is her Hash Brown Casserole. My husband and I always looked forward to Easter and Thanksgiving meals at his parents’ house, which had to include that decadent side dish from the 50s era. Man, is it good!

  3. Combine the hash browns, bacon bits, sour cream, shredded cheddar cheese, and the cream of chicken sauce. Place in a casserole dish.
  4. Sprinkle a little more cheese on top…because why not?!…and bake until golden and bubbly.

Description

This creamy, comforting Hash Brown Casserole is made from scratch, requires no canned cream soup, and is gluten-free. Perfect side for a holiday table!


Ingredients

  • 1 cup low-sodium chicken broth
  • 1/2 cup half and half
  • 3 tablespoons corn starch
  • 1 1/2 teaspoons dried parsley, crushed in hand
  • 1/2 teaspoon poultry seasoning
  • 1 teaspoon Kosher salt (use an addition 1/2 teaspoon, if not using bacon)
  • 3/4 teaspoon ground black pepper
  • 5 tablespoons butter, divided
  • 1/2 yellow onion, diced
  • 2 garlic cloves, minced
  • 1 (30 ounce) bag of shredded hash browns, thawed
  • 1 (16 ounce) container sour cream (recommended: full-fat Daisy brand)
  • 2 cups (8 ounces) shredded Colby Jack cheese (or your favorite shredded cheese)
  • 1 pound bacon (try baking your bacon for easy clean up)

 


Instructions

  1. Preheat the oven to 350°F. Grease an 9×13 casserole dish with butter or cooking spray.
  2. In a glass measuring cup, whisk together the chicken broth, half and half, cornstarch, parsley, poultry seasoning, salt, and pepper. Set aside.
  3. Heat 1 tablespoon butter in a medium saucepan over medium-high heat. When the butter is melted, add the onions and saute until translucent, about 3 minutes. Stir in the garlic at the end for about 30 seconds, until fragrant.
  4. Whisk in the creamy cornstarch mixture to the onions. Bring to a simmer, stirring constantly until thick and creamy, about 2-3 minutes. Remove from the heat, stir in the remaining 4 tablespoons butter, and let cool.
  5. In a large mixing bowl, stir together the thawed hash browns, sour cream, cheese, bacon, and the cooled cream sauce. Place in the casserole dish, smoothing it out evenly. (Note: At this point, you can cover and refrigerate for up to 3 days.)
  6. Bake for about 45 minutes, until edges are bubbly and top is golden.

    Growing up, my mom made a similar hash brown casserole that was my holiday FAVORITE. This recipe caught my eye because it reminded me of that nostalgic recipe, and I could eat it with my gluten allergy. It did not disappoint! I skipped the bacon, because we were having with ham, but I’m sure it would be delicious with it as well. I cut the recipe in half since we had so many sides, and there was still plenty for my extended family of 6 adults and 2 kids.

    Made this again using an 8oz bag of swiss gruyere cheese. We were snowed in and I didn’t have any bacon or onion. Left out any butter other than greasing casserole dish. Again, no pre-thickening. It was fantastic! So thankful for this recipe. My daughter has been very negative about going gluten free and she loves hashbrown casserole. Recipes like this really help!

    We enjoyed this recipe. I did not pre-thicken the broth mixture on the stovetop and it thickened up nicely as it baked. I did find it a bit too cheesy for my tastes and will probably halve the cheese next time. I used sharp cheddar and it also came out too oily, so I will also leave out the extra butter. I only had 3 pieces bacon, so I sauteed it with the veg, but the cheese covered up the other flavors. I will definitely try again with modifications, and now I have a liquid to corn starch ratio to use in other casseroles as well.

      Hi Maegan. I’ve never tried fully cooking and freezing the whole casserole, so I’m not sure how it would do. Sorry! Thanks for leaving a comment. I’m so glad you like our book.
