How to Make Low Carb Green Bean Casserole

Alright, let’s plunge into the deliciousness of making this Low Carb Green Bean Casserole. First things first, grab your trusty skillet and melt 2 tablespoons of butter over medium heat. Once that buttery goodness starts to bubble, toss in 1/2 medium yellow onion, sliced into rings, along with 2 stalks of celery, sliced small, and 4 ounces of drained mushroom stems and pieces.
You want to sauté these beauties until they’re nice and soft, which should take about 7 to 8 minutes. I always find that this step fills the kitchen with the most heavenly aroma—seriously, it’s like a cozy hug for your senses. Just be careful not to let those onions burn; nobody wants a bitter taste ruining the party.
While those veggies are getting all tender and aromatic, let’s mix up the creamy goodness. In a separate bowl, combine 1/4 cup of heavy cream with 1/4 cup of mayonnaise. I know, it sounds a little rich, but trust me, this duo is what makes the casserole creamy and dreamy.
Once that’s all mixed together, it’s time to bring everything together. In a large casserole dish, combine your sautéed vegetables with 2 (15 ounce) cans of drained French style green beans, the creamy mixture, and 1 cup of your favorite diced cheese—you can’t go wrong with cheddar, jack, or pepper jack here.
Sprinkle in 3/4 teaspoon of salt, 1/2 teaspoon of pepper, and 1/2 teaspoon of garlic powder for that extra kick. Now, spread everything evenly in the casserole dish and pop it in the oven at 350°F.
Cover it and let it bake for about 30 minutes. This is your moment to kick back and maybe grab a cup of coffee while you wait. If you like your casserole a little crispy on top (who doesn’t?), uncover it for the last few minutes to let it brown up.
When it’s ready, take it out and let it cool for just a minute before jumping in. I promise, every bite will be a warm hug from your oven, and you might just find yourself going back for seconds—don’t worry, I won’t judge. Enjoy your cozy creation; it’s well worth the effort!
Low Carb Green Bean Casserole Substitutions & Variations
While the classic Low Carb Green Bean Casserole is a delight on its own, experimenting with substitutions and variations can elevate it to new heights.
For instance, I love using fresh green beans instead of canned for a crunchier texture. If you’re looking to switch up flavors, try adding sautéed mushrooms or even bacon bits.
For a dairy-free version, coconut cream works wonders in place of heavy cream. You can also swap mayonnaise for Greek yogurt for a tangy twist.
Don’t hesitate to mix different cheeses, too—pepper jack adds a delightful kick! Enjoy making it uniquely yours!
Additional Tips & Notes
To guarantee your Low Carb Green Bean Casserole turns out perfectly, I recommend prepping all your ingredients before you start cooking. This not only saves time but assures everything’s ready to go.
If you want a crunchier topping, consider adding crushed pork rinds or almond flour mixed with cheese before baking. Don’t forget to taste as you go; adjusting seasonings can elevate the dish.
If you have leftovers, store them in an airtight container in the fridge for up to three days. Reheating in the oven can help maintain the texture. Enjoy this delicious twist on a classic!
