Sausage & Spinach Casserole – Keto / Low Carb

Sharing is caring!

spinach sausage casserole

This sausage and spinach casserole literally came to be because we were headed out for vacation and had to clean out the fridge. I did not even think this would be as delicious and easy as it was. And it’s low carb / keto friendly – it’s also an easy meal prep casserole.

The pic above and below is chopped sausage. If you really want to keep this keto, I’d go with a sausage like Aidells Chicken and Apple Sausage or another sugar free option. Easy keto casserole is the way to go!

And it was also gone in one day. But who’s counting! I’ve added some process shots so you can see how I made it. But it’s so easy, you won’t need them. If you want to jump to the actual recipe, just keep scrollin’!

How to make a sausage & spinach casserole

saute sausage

Cook the chopped sausage in the pan over medium heat, but don’t overcook. Once you remove the sausage, saute some chopped onions. I used a small onion, but you may want more depending on your love of onions. If you are a garlic person, go for it – I am not. I also didn’t add spices, but I imagine you could try some different savory ones – I think next time I’ll add nutmeg and cinnamon – it’s a new fave and I’ve tried it in my chicken spinach artichoke casserole with great success! Easy keto casseroles are my favorite!

dd egg mixture to sausage spinach ingredients

Add the sausage, onions, sour cream and cheeses to a medium size bowl. Whisk the eggs and some milk or heavy whipping cream – either will do. Add that to the sausage mixture and stir until mixed.

Add the fresh spinach at this point. Blend it just enough to work it through the mixture.

Spread the sausage and spinach mixture into an 8×8 baking dish. You could use a 13×9 and it wouldn’t be quite as deep – but would cook fine. Top with some extra cheese (please!) and bake.

Did anyone else that has made this feel like this was a breakfast dish vs a dinner? The egg definitely was dominate in this, making it seem more like breakfast. Not that I mind breakfast for dinner, just wasn't expecting it nor could see using the same sausage if I made it again. I'd use breakfast sausage.
