How to Make Cheddar Bay Green Bean Casserole
Step 1: Prep the Green Beans
Bring a big pot of salted water to a rolling boil. Drop in your trimmed and halved green beans and let them blanch for just 3 to 4 minutes, so they stay bright green and crisp-tender. Drain the beans and immediately shock them in a bowl of ice water. This stops the cooking and locks in their gorgeous color. Once cool, drain thoroughly and set aside—you want them dry so your casserole isn’t watery.
Step 2: Sauté the Aromatics
In a roomy skillet over medium heat, melt 1 tablespoon of butter. Sauté your chopped onion for 3 to 4 minutes until it softens and turns translucent, releasing its sweetness. Toss in the minced garlic and cook for just 30 seconds until fragrant. Remember, garlic cooks fast—the goal is gentle flavor, not a browned, bitter mess. Remove from the heat to cool just a bit.
Step 3: Mix the Filling
Grab a large mixing bowl. Combine the cream of mushroom soup, sour cream, sharp cheddar cheese, sautéed onion and garlic, Old Bay seasoning, salt, and pepper. Stir until creamy and uniform. Now, gently fold in your blanched green beans, making sure each piece is thoroughly coated with cheesy, savory sauce. This is where Cheddar Bay Green Bean Casserole starts smelling like the holidays already!
Step 4: Assemble the Casserole
Lightly grease a 9×9-inch (or similar) baking dish. Pour in your green bean mixture and smooth out the top, ensuring an even layer. In a small bowl, mix the Cheddar Bay biscuit mix (or your crushed cheesy biscuit crackers) with melted butter. Stir until the mix is crumbly, then sprinkle this buttery, garlicky goodness all over your casserole to create that classic, golden topping.
Step 5: Bake Until Bubbling
Slide your dish into a preheated 375°F (190°C) oven. Bake for 25 to 30 minutes, until the topping is golden brown and crisp, and you see the cheesy filling bubbling at the edges. Let it cool for about 5 minutes before serving—if you can stand the wait! That’s when the flavors settle, and the slices come out perfectly.
How to Serve Cheddar Bay Green Bean Casserole

Garnishes
Add the finishing touch with a light sprinkle of extra shredded cheddar cheese or a dusting of fresh herbs like parsley or chives. For a little kick, crack some black pepper or add a dash of extra Old Bay. These vibrant green notes and colorful pops make your Cheddar Bay Green Bean Casserole look as fresh as it tastes.
Side Dishes
This cheesy, crunchy beauty fits in at any feast, pairing especially well with roast turkey, glazed ham, or even baked tofu for vegetarian tables. Round out the plate with fluffy mashed potatoes, herby stuffing, or a crisp green salad. The savory-cheesy flavors of Cheddar Bay Green Bean Casserole absolutely shine with all your holiday favorites.
Creative Ways to Present
Think beyond the basic baking dish! For a playful twist, scoop and serve your Cheddar Bay Green Bean Casserole into individual ramekins—perfect for dinner parties. Or pile leftovers onto sourdough toast for a savory brunch. Mini cast iron skillets give that vintage, homey feel that makes guests swoon. However you plate it, this casserole is made to steal the show.
Make Ahead and Storage
Storing Leftovers
Cheddar Bay Green Bean Casserole keeps beautifully! Store any leftovers in an airtight container in the refrigerator for up to 3 days. The flavors meld and intensify, and you’ll enjoy those crispy, cheesy bits even more the next day.
Freezing
You can freeze the assembled, unbaked casserole wrapped tightly in foil and plastic for up to 1 month. When ready to enjoy, let it thaw overnight in the fridge before baking as usual. For baked leftovers, freeze individual portions for easy reheating—just note the topping may soften a bit but will crisp up again in the oven.
Reheating
For best results, reheat your Cheddar Bay Green Bean Casserole in a 350°F oven, covered with foil for the first 10 minutes, then uncovered to crisp the topping. Individual servings can also be microwaved, but the oven method best preserves the coveted crunch.
FAQs
Can I use frozen green beans instead of fresh?
Absolutely! Just make sure to thaw and dry them well before using, so your casserole doesn’t get watery. Fresh is ideal for texture, but frozen green beans are a convenient and still delicious alternative.
What can I substitute for Cheddar Bay biscuit mix?
If you can’t find Cheddar Bay biscuit mix, simply crush up cheesy crackers or use seasoned breadcrumbs with extra shredded cheddar and garlic powder. The goal is a crispy, cheesy topping, so feel free to get creative!
Is it possible to make this Cheddar Bay Green Bean Casserole gluten free?
Definitely! Use a gluten-free cream of mushroom soup and swap in your favorite gluten-free biscuit mix or crackers for the topping. Always double-check your labels to be sure everything is safe for your needs.
Can I make this casserole ahead of time?
Yes—prepare the filling and topping separately, cover, and refrigerate the unbaked casserole for up to 24 hours. Add the topping just before baking so it stays crisp and fresh.
What else can I add to jazz up the casserole?
A handful of chopped cooked bacon or crispy fried onions mixed with the topping can add even more big flavor and crunch. Fresh herbs, diced pimentos, or a sprinkle of smoked paprika also make fun additions.
Final Thoughts
If you’re on the lookout for a comforting, crowd-pleasing side that feels both familiar and brand new, give Cheddar Bay Green Bean Casserole a try. Every bite will remind you why some dishes are worth celebrating all year round. Your table is about to get a whole lot cozier—enjoy!
