Now this, this is the type of skillet dinner we live for here at Cast Iron Keto. One skillet, a few simple ingredients, and BAM, you've got a dinner that's worthy of anyone's praise. This Keto Bangers and Mash with Onion Gravy recipe is so comforting, hearty, and just all around perfect.

We've got 3 layers of goodness in this skillet:

1. garlic butter and herb mashed cauliflower
2. onion gravy
3. Kiolbassa Polish Style Smoked Sausages

Can you even??

While our thing is one-pan dinners, technically, you can indeed make this recipe with multiple pans/pots if you want to move even quicker. We try to keep a minimalist kitchen so using our handy cast-iron skillet for each component works well for us but it does get a bit into the musical skillet territory while you transfer each component into and out of the skillet before pilling it all back in to take a bake under the broiler.

Either way, it's bound to be delicious.

Let's chat about each layer, shall we?

Garlic Butter and Herb Mashed Cauliflower

The single best-mashed cauliflower recipe, EVER, we promise. This is roughly the recipe we used in multiple recipes in our book and it gets rave reviews from everyone who tries it. Think you like mashed potatoes? Think again because this cauliflower will convert you for LIFE, Keto or not.

Kiolbassa Polish Style Smoked Sausages

No nitrates, preservatives, no MSG, and no gluten - these smoked sausages are always our go-to for a Bangers and Mash style meal. Made with a blend of pork and beef, these sausages are so flavorful, brown perfectly, and make this delicious skillet dinner a snap.
