Grandma’s Onion Squares Ingredients
• Let’s gather what you need to create this comforting dish!
For the Crust
- All-Purpose Flour – Provides structure for the crust; substitute with gluten-free flour for a gluten-free version.
- Baking Powder – Acts as a leavening agent, helping the crust rise; no substitutions recommended.
- Salt – Enhances the flavor of the crust and filling; use kosher salt for best results.
- Butter (softened) – Adds richness and flavor to the crust; can be replaced with vegan butter for a dairy-free option.
For the Filling
- Onions – The star ingredient, providing sweetness when caramelized; fresh onions are preferable, but frozen work in a pinch.
- Cream Cheese – Adds creaminess and stability to the filling; substituting with ricotta offers a different texture.
- Sour Cream – Contributes tanginess and moisture; plain Greek yogurt can be used for a lighter option.
- Eggs – Binds the filling together; can be replaced with flaxseed meal mixed with water for a vegan option.
- Cheddar Cheese – Adds a savory, melty element to the filling; mozzarella or Swiss cheese can be swapped based on preference.
Step‑by‑Step Instructions for Grandma’s Onion Squares
Step 1: Prepare the Crust
In a large mixing bowl, whisk together the all-purpose flour, baking powder, and salt until combined. Next, add the softened butter, blending with your fingers or a pastry cutter until the mixture resembles coarse crumbs. Press this dough firmly into a greased 9×13-inch baking dish and bake in a preheated oven at 350°F (175°C) for 12-15 minutes, until the crust is lightly golden.
Step 2: Caramelize Onions
While the crust bakes, heat a skillet over medium heat and add a drizzle of oil or butter. Slice the onions thickly, then add them to the pan. Cook for about 10-15 minutes, stirring occasionally, until the onions are soft and golden brown, releasing their natural sweetness. Once caramelized, remove the skillet from the heat and allow the onions to cool down slightly.
Step 3: Make the Filling
In a large bowl, combine the cream cheese, sour cream, and eggs, whisking them together until smooth and creamy. Gradually mix in the shredded cheddar cheese, ensuring it’s well incorporated. Gently fold in the cooled caramelized onions, combining the ingredients thoroughly to create a rich, savory filling for your Grandma’s Onion Squares.
Step 4: Combine and Bake
Pour the cheese and onion filling evenly over the pre-baked crust in the baking dish. Carefully spread it out with a spatula to ensure an even layer. Place the dish back into the oven and bake for an additional 25-30 minutes. The filling should be set, and a golden top will form. To check doneness, insert a toothpick; it should come out clean when ready.
Step 5: Cool and Serve
Once baked, remove the dish from the oven and let the squares cool for about 10 minutes. This resting time allows the filling to set for easier cutting. Using a sharp knife, cut the Grandma’s Onion Squares into squares, serving them warm or at room temperature for a delightful comfort food experience.
