The Hidden Gluten in Traditional Casseroles
On the surface, a casserole made of potatoes, cheese, and sour cream might seem safe for a gluten-free diet. However, many traditional recipes, including the popular 'funeral potatoes,' rely on ingredients that contain hidden gluten. The most common culprits are canned cream soups, such as cream of chicken or cream of mushroom, which use wheat flour as a thickener. In some cases, the crunchy topping that adds texture to the dish, like crushed crackers or cornflakes, also contains wheat. Even the frozen hash browns themselves can be a risk, as some brands add flour or are processed in facilities with a high risk of cross-contamination.
Potential Gluten Sources in Cheesy Hashbrown Casserole
To ensure your casserole is truly gluten-free, it is vital to scrutinize every component. Here are the main areas to watch:
- Canned Cream Soup: The most significant source of hidden gluten. Popular brands like Campbell's use wheat flour. Some certified gluten-free options exist, but many homemade substitutes are more flavorful and reliable.
- Frozen Hash Browns: While potatoes are naturally gluten-free, some frozen hash brown products are processed with wheat flour or risk cross-contamination. Always check for a 'Certified Gluten-Free' label on the package. Brands like Simply Potatoes are often cited as safe options.
- Crunchy Toppings: Traditional toppings like crushed butter crackers or cornflakes are not gluten-free. Alternatives such as crushed gluten-free crackers, certified gluten-free cornflakes, or even bacon bits can be used instead.
- Chicken or Vegetable Broth: If you choose to make your own cream soup substitute using broth, ensure you select a brand that is labeled gluten-free.
Building a Delicious, Gluten-Free Cheesy Hashbrown Casserole
Creating a gluten-free version of this classic comfort food is straightforward and yields a dish that is often fresher and more flavorful than its traditional counterpart. The key is making a simple homemade cream sauce from scratch.
A Simple Gluten-Free Recipe
This recipe replaces the canned soup with a homemade, cornstarch-thickened sauce for a rich and creamy result.
Ingredients:
- 1 (30-ounce) bag of certified gluten-free shredded hash browns, thawed
- 1/4 cup unsalted butter
- 1/4 cup cornstarch or gluten-free flour blend
- 2 cups milk (dairy or non-dairy)
- 1 cup gluten-free chicken or vegetable broth
- 16 ounces sour cream or plain Greek yogurt
- 2 cups shredded sharp cheddar cheese, divided
- 1/2 teaspoon garlic powder
- 1/2 teaspoon black pepper
- 1/2 cup gluten-free crispy rice cereal or crushed gluten-free crackers, for topping
- 2 tablespoons butter, melted, for topping
Instructions:
- Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish.
- In a medium saucepan, melt 1/4 cup of butter over medium heat.
- Whisk in the cornstarch and cook for one minute to create a roux.
- Slowly whisk in the milk and broth until smooth. Bring the mixture to a boil, whisking constantly until it thickens.
- Remove the saucepan from the heat and stir in the sour cream, 1 cup of the shredded cheese, garlic powder, and black pepper until fully combined and the cheese is melted.
- In a large bowl, combine the thawed hash browns with the creamy cheese sauce.
- Pour the mixture into the prepared baking dish and spread evenly. Top with the remaining 1 cup of shredded cheese.
- In a small bowl, mix the crushed gluten-free cereal with the 2 tablespoons of melted butter and sprinkle over the top of the casserole.
- Bake for 45-60 minutes, or until the edges are bubbly and the top is golden brown and crispy. Let it sit for 10 minutes before serving.
