Ingredients
Instructions
- Preheat oven to 450°F; grease an 8 x 8 x 2-inch square pan.
- In a skillet, cook sliced onions with 1/4 teaspoon salt and pepper in hot shortening until tender and golden.
- Set the cooked onions aside.
- Roll the biscuit dough into a 10-inch square and firmly pat it into the bottom and sides of the prepared pan.
- Spread the cooked onions evenly over the dough.
- In a small bowl, beat the egg, sour cream, and 1/4 teaspoon salt together.
- Pour the egg mixture over the onions.
- Bake for about 20 minutes or until lightly browned.
- Cut into squares and serve warm.
Tips & Substitutions
For the best flavor, let the cooked onions cool slightly before spreading them on the dough. You can substitute vegetable oil for shortening if preferred. If using pre-made biscuit dough, consider adding a pinch of garlic powder to enhance the flavor. Adjust the seasoning to taste, and for a richer flavor, try adding some shredded cheese on top before baking.
Serving Suggestions
These squares are best served warm and can be enjoyed as a snack or appetizer. They pair wonderfully with a side salad or a bowl of soup for a light lunch or dinner. For an added twist, serve with a dollop of sour cream or a light yogurt-based sauce. Browse more American recipes for additional meal ideas.
Storage & Reheating
Store leftover Onion Biscuit Squares in an airtight container in the refrigerator for up to 3 days. To reheat, place squares in a preheated oven at 350°F for about 10-15 minutes until warmed through. You can also microwave them for 30-60 seconds, but the oven method helps retain their crispiness.

Frequently Asked Questions
Can I use frozen onions instead of fresh?
Yes, you can use frozen onions, but be sure to thaw and drain them well to avoid excess moisture. This will help prevent the biscuit squares from becoming soggy.
What can I use instead of sour cream?
Greek yogurt makes an excellent substitute for sour cream, adding a similar tangy flavor and creamy texture. You can also use buttermilk for a lighter option.
Can I add other ingredients to the filling?
Absolutely! Feel free to add chopped bell peppers, cooked bacon, or shredded cheese to the onion mixture for extra flavor. Just be mindful of the moisture content to ensure the biscuit squares bake properly.
