Step‑by‑Step Instructions for Grandma’s Onion Squares
Step 1: Prep the Oven and Dish
Begin by preheating your oven to 375°F (190°C). While it warms up, prepare your baking dish by greasing it generously with butter or lining it with parchment paper. This step is essential to ensure your Grandma’s Onion Squares don’t stick and come out looking golden and perfect.
Step 2: Sauté the Onions
In a skillet over medium-low heat, melt a few tablespoons of butter. Add the chopped onions and a pinch of salt, stirring occasionally. Sauté for about 8–10 minutes until the onions are soft and golden, releasing their sweet aroma. This caramelization will infuse your onion squares with deep flavor, making them irresistible.
Step 3: Prepare the Dough
In a large bowl, whisk together your flour, baking powder, and salt until well combined. In another bowl, mix the melted butter, milk, and egg until smooth. Gradually add the wet mixture to the dry ingredients, stirring gently until just combined. Be careful not to overmix, as this can toughen your dough for the Grandma’s Onion Squares.
Step 4: Assemble and Bake
Spread the prepared dough evenly in your greased baking dish, smoothing it to the edges. Spoon the sautéed onions over the dough, then sprinkle with cheese if you’re using it. Place in the preheated oven and bake for 25–30 minutes, or until the top is golden brown and the edges are crisp. Your kitchen will smell heavenly!
Step 5: Cool and Serve
After baking, remove the dish from the oven and let it cool for about 5 minutes. Once slightly cooled, slice into squares, revealing the soft, sweet layers inside. Serve warm, and get ready to share these delightful Grandma’s Onion Squares with family and friends!
