I put too much pepper in a cauliflower puree one time and was surprised how much it tasted like KFC gravy. I mean, if I can check all my gravy boxes without the flour, fat, or cornstarch, that works for me. Skip the wine and it's even keto friendly.
What you will need
1 yellow onion
1 pt crimini mushrooms
1 head cauliflower
2 cloves garlic
1/4 cup red wine
How to cook
Slice the onion. Clean and slice the mushrooms. Quarter the cauliflower and remove the leaf end.
Cook the onion and mushroom down gently in a little olive oil over medium low.
In a sauce pot, submerge cauliflower in cold water. Cover and bring to a boil. Remove from heat.
Slice the garlic and add it to the onion sautee. Stir it up, then add the red wine and reduce.
Move the cauliflower to a blender. Reserve the cooking liquid.
Add the sauteed onion and mushroom.
Blitx that mixture, adding a little of the reserved cauliflower liquid at a time, until you get the consistency of a thick gravy.
Season and serve
Season with salt and pepper. I like to go real heavy on the black pepper here. It woks well with the cauliflower. If you hit it with enough fresh black pepper, it tastes a lot like KFC gravy.
