Some Tips on This Brenda Gantt’s Onion Casserole Recipe
1. Pick Big, Sweet Onions
Use big onions like Vidalia onions if you can. They get nice and sweet when you cook them!
2. Cut Onions Evenly
Try to slice your onions all the same size. This helps them cook the same way and makes your casserole yummy.
3. Save That Bacon Grease
Don’t throw away the bacon grease! You can use it later to cook eggs or veggies.
4. Soften Cream Cheese First
Warm your cream cheese in the microwave for 10 seconds. It mixes better when it’s soft!
5. Don’t Skip the Pimentos
Put those little red pimentos in your casserole. They add pretty color and tasty flavor.
6. Use a Big Bowl
Mix everything in a big bowl so nothing spills out. It makes cleaning up easier too!
7. Taste Before Baking
Take a tiny taste of your mix before baking. Add a pinch more salt or pepper if you need it.
8. Cover with Foil
Don’t forget to cover your dish with foil before baking. This keeps it moist and creamy.
9. Use Fresh Cheese
Grate your cheese from a block instead of using bagged cheese. It melts so much better!
10. Let It Cool a Little
After baking, let your casserole sit for 5 minutes. It will be easier to scoop and taste even better!

Notes
Common Queries on This Brenda Gantt’s Onion Casserole Recipe
Here, we’ve got you covered with some common questions about the Brenda Gantt’s Onion Casserole that people often ask.
1. Are casseroles popular in the South?
Oh honey, absolutely! Down here in the South, casseroles are a staple at just about every gathering-from church potlucks to Sunday suppers. We love how easy they are to make ahead, how they feed a crowd, and how comforting they are. An onion casserole like this one is a perfect example of Southern hospitality on a plate.
2. What are the best onions for casserole?
From our kitchen experience, sweet onions like Vidalia onions are the best for casseroles. They get beautifully tender and sweet when cooked, adding rich flavor without overpowering bitterness. If you don’t have Vidalias, yellow onions or even white onions will work fine.
3. What’s casserole good for?
Casseroles are great when you need a hearty, make-ahead dish that feeds a bunch of hungry folks. They’re perfect for holiday meals, weeknight dinners, family reunions, or anytime you want something warm, comforting, and easy to serve. Plus, they’re fantastic for leftovers!
4. Can I make this onion casserole ahead of time?
Yes ma’am! We’ve found this casserole tastes just as good (or even better) when you make it ahead. Assemble everything, cover it, and keep it in the fridge until you’re ready to bake. Just pop it in the oven when your guests arrive, and you’re set.
5. Do I need to use whole milk?
While the original recipe calls for whole milk, we’ve used 2% plenty of times when that’s all we had in the fridge. It still turns out creamy and delicious. The cream cheese helps keep it rich, so don’t worry if you don’t have whole milk on hand.
6. Can I add other vegetables to this casserole?
Sure can! We’ve tried adding thinly sliced mushrooms or even a handful of cooked spinach, and it turned out great. Just be mindful not to add too much moisture, or the casserole might get runny.
7. Is it necessary to cover the Brenda Gantt Onion Casserole while baking?
From our experience, covering it for the first 30 minutes helps the onions get soft and the flavors meld together. Uncovering it at the end lets the cheese melt and brown just right. Don’t skip this step-it’s the secret to that perfect texture!
8. Can I freeze Brenda Gantt Onion Casserole?
We don’t usually freeze it because the texture of the onions can get a little mushy after thawing. But if you have a lot left over, you can freeze portions in airtight containers for up to a month. Just reheat gently in the oven.
9. What kind of cheese works best?
Sharp cheddar is our go-to for its bold, tangy flavor. But we’ve also tried Colby Jack and mozzarella in a pinch, and they were tasty too. Just stick with cheeses that melt well and give a good cheesy finish.
10. How do I know when the casserole is done?
You’ll know it’s ready when the onions are fork-tender, the edges are bubbling, and the cheese on top is melted and golden. If you see these signs, pull it out of the oven and let it rest for a few minutes before serving.
This Brenda Gantt Onion Casserole Recipe is more than just a side dish-it’s a warm, cheesy hug on a plate! Perfect for family dinners, holiday gatherings, or potlucks, it’s sure to impress everyone at your table.
