Biscuit Casserole Beginnings: From Granny’s Table to My Recipe Notebook
A Southern Tradition, With a Twist
I’m MacMar—a Charleston-born-and-raised flavor fanatic—and this biscuit casserole brings me back to the sun-drenched afternoons spent in my Granny’s kitchen. I grew up learning to cook less by measurements and more by instinct—smelling onions sizzle in cast iron, judging dough textures with my fingertips, and listening to the subtle cues of a bubbling oven-baked masterpiece.
This biscuit casserole isn’t your cafeteria version. Instead, it’s a creamy, savory base of sausage, cheese, and vegetables blanketed beneath clouds of golden homemade biscuits. It’s the kind of dish that smells like comfort and feels like a hug—just with a little more crunch on top.
The recipe came together out of necessity: a fridge full of leftovers, a craving for comfort, and a restless urge to try something new. The result? A buttery biscuit-topped casserole so good it made our meal rotation instantly. I’ve since brought it to farmers’ market brunches, impromptu potlucks, and even showcased it on a local food truck menu.
And the best part? You don’t need fancy gear or hard-to-pronounce ingredients to make this gorgeous dish come together—just bold flavor, tried-and-true techniques, and that famous Southern patience.
Why Biscuit Casseroles Are Here to Stay

This version keeps the comfort factor high while tweaking just enough to keep things interesting—fresh herbs, a touch of heat, and a crisp-on-the-outside biscuit topping baked right on your filling. Consider it my take on the ultimate lazy-day-meets-Sunday-best dish. In fact, you’ll also see flavors echoing the spirit of my plant-based comfort bowl—hearty, rich, but absolutely achievable for cooks at any level.

Let’s Cook: Step-by-Step
- Preheat oven to 375°F. Lightly grease a 9×13” baking dish.
- In a skillet over medium heat, cook sausage until browned. Drain excess grease.
- Add onion and bell pepper. Sauté 5 minutes until softened. Stir in spinach.

- Gradually add in milk, stir constantly until it thickens (about 2-3 minutes).
- Stir in salt, pepper, garlic powder, paprika, and cheddar cheese. Mix until melted.
- Pour mixture into your baking dish.
- Arrange biscuit dough over the top. Leave space between them—they’ll expand as they bake.

Tip: Brushing the biscuits with a mix of melted butter and finely chopped herbs adds a wow factor worthy of your fanciest brunch spread or garlic-lovers’ side dishes.
Biscuit Variations and Flavor Boosts
Homemade Biscuit Options for Extra Lift
While store-bought dough works well, nothing beats the flaky mountain of flavor you get from scratch-made biscuits. The trick to fluffy biscuits? Super-cold butter and a light touch.
Try this quick fix:
- 2 cups all-purpose flour
- 1 tbsp baking powder
- 1/2 tsp salt
- 1/4 cup cold grated butter
- 3/4 cup buttermilk
Mix dry ingredients, cut in butter, gently fold in buttermilk. Drop spoonfuls on top of your filling and bake the same way. For an in-depth guide, see the USDA baking basics for home cooks.

Bold Twists to Elevate the Dish
Add kale and sun-dried tomatoes for Mediterranean flair. Swap sausage for buffalo tofu and slather with ranch drizzle for Game Day. Breakfast version? Crack in a few eggs before baking and let them poach in the creamy base.
Get creative—this one’s hard to mess up.
FAQs: Biscuit Casseroles Demystified
Is it better to use butter or Crisco for biscuits?
Butter wins for flavor. It offers better lift and those dreamy pockets of steam that create flaky biscuits. Crisco may offer more consistency, but for our biscuit casserole, stick with cold, unsalted butter.
What is the secret to fluffy biscuits?
Cold ingredients and minimal handling. Don’t overwork the dough, and always chill your butter to help create steam during baking for sky-high fluff.
What is famous for Cheddar Bay biscuits?
Cheddar Bay Biscuits are a Red Lobster staple—packed with cheese, garlic, and brushed with herb butter. For a similar effect, add cheddar and garlic powder to your biscuit dough and serve with melted herb butter.
Why do you have to refrigerate breakfast casserole overnight?
Overnight refrigeration allows flavors to meld and ensures even soaking of ingredients like bread or egg. For our biscuit casserole, no need for overnight unless adding eggs or prepping ahead.
