When you have extra squash on hand, try making a summer squash casserole, Southern style. Topped with buttermilk biscuits it’s a vegetable casserole that even the kids will love.
It’s that time of year when we have more squash than we know what to do with. I love it just steamed in the microwave, but that’s not my family’s preference. I’ve baked it in macaroni and cheese and grated it in a quiche, but I’m always struggling for ways to get them to eat more vegetables. Making it into a cobbler with biscuits on top was a winner.
Everyone loves a cobbler even when there are vegetables underneath instead of fruit. My gang gave it a try and actually liked it. I mixed some onions and corn with the squash to change up the texture, and then added some cheesy buttermilk biscuits.
This is filling enough for a meal. If you’re vegetarian, you can leave out the chicken stock or use vegetable stock instead.
Pro Tip: Make sure you cook the cobbler long enough for the biscuits in the center to be cooked through, you don’t want them to be doughy.

What you’ll need
- Zucchini & Yellow squash – wash and dice your veggies into bite sized pieces

- Vidalia onion – this is a sweeter onion and is versatile in cooking and pairing up with squash
- Chicken stock – you can use stock or broth or substitute vegetable broth
- Lemon juice – just a little goes a long way
- Cheeses – parmesan and white cheddar cheese give a nice bite to the biscuits
- Chives – similar to a green onion, there is no white portion to the bottom of the onion but still have great flavor
- Butter cold – leave the butter for your biscuit dough in the fridge after you’ve measured so it stays cold
- Buttermilk – if you don’t have any buttermilk on hand, place one tablespoon of lemon juice in a measuring cup and fill it up to 1 cup, then let it sit 5+ minutes until it curdles
- Pantry staples – butter flour, baking powder, salt, pepper
