Cauliflower Risotto Keto Recipe (5g Net Carbs)
This cauliflower risotto delivers the creaminess of arborio-based risotto at 5g net carbs per serving instead of the traditional 45g. Ready in 25 minutes for 4 servings, with 380 calories, 12g protein, and 32g fat each. Riced cauliflower and broccoli simmered in heavy cream and finished with sharp cheddar and parmesan. Built for keto, low-carb, gluten-free, and diabetic-friendly eaters who want the Italian comfort of risotto without spiking blood sugar.
Why This Works on Keto
Arborio rice runs 45g of carbs per cup cooked. Riced cauliflower runs 5g per cup and carries a neutral flavor that absorbs cream, butter, and cheese the way rice absorbs stock. The starch that gives real risotto its glossy hang comes from the arborio releasing amylopectin as it cooks.
Here we mimic that texture with heavy cream reduced by a third and a heavy hit of grated cheese. The cheese proteins tighten the sauce as it cools and coat every grain of cauliflower the same way a mantecatura finish would in an Italian kitchen.
Broccoli adds contrast in color and texture and stays inside the carb budget at 2g per 1/2 cup. Total macros land near 75% fat, 12% protein, 13% carbs.

Cauliflower Risotto Keto Recipe
Ingredients
- 1/2 medium cauliflower
- 10 fl. oz. vegetable broth
- 4 tsp. butter
- 1/2 medium carrot
- Broccoli 2 tbsp
- Onion 1, medium
- 3 1/2 fl. oz. heavy cream
- 2 garlic cloves
- 1 1/4 tbsp. cheddar cheese
- Salt and pepper to taste
Topping
- 1 tbsp. olive oil
- 1/2 lemon grated lemon peel
- Black pepper to taste
Instructions
- Start by separating the cauliflower into florets. Use only the soft parts of the cauliflower leaves, finely chop them, and set them aside. Chop the onion, garlic, and carrot into fine cubes. Finally, cut the broccoli into tiny florets.
- Place only the cauliflower florets in a blender and process until the cauliflower resembles grains of rice.
- Preheat a large skillet. Add butter to the skillet. When the butter starts to melt, add the onion and garlic with a pinch of salt. Once the onion and garlic begin to cook, add the chopped cauliflower leaves and continue frying. Then, add the broccoli florets and fry for a while. Finally, add the processed cauliflower and another pinch of salt, and continue frying.
- While the vegetables are roasting, add two ladles of vegetable broth. After adding the vegetable broth, reduce the heat and continue cooking. After cooking for a while, check the cauliflower for doneness by tasting it. Add black pepper once the vegetables are cooked. Next, add heavy cream while the risotto is still cooking on low heat. Mix lightly and turn off the stove.
- Remove the skillet from the heat, and while it is still hot, grate cheddar cheese over the risotto and stir gently. Transfer the risotto to a serving plate, grate some lemon zest over it, and drizzle with olive oil as a final touch.

Ingredient Notes
Rice the cauliflower fresh in a food processor to a coarse rice-grain size. Pre-riced frozen cauliflower works in a pinch but releases more water and the finished dish loses body. Squeeze the riced cauliflower in a clean towel to remove moisture before cooking; this is the single most important step.
Heavy cream at 40% butterfat only. Half-and-half or lower-fat cream will not reduce properly and separates. Aged sharp cheddar (Cabot 3-year, Kerrygold Reserve) melts smoother than mild cheddar and adds tang. Parmesan from a wedge, grated fine. Skip pre-shredded cheeses coated in potato starch.
Bone broth or chicken stock at 0g carbs to loosen the sauce if it tightens too much. Season aggressively with salt; cauliflower needs more than rice does.

Tips and Variations
Saute the riced cauliflower in butter for 4 minutes before adding cream to drive off residual water and build a slight toasted note. Add cream and simmer 8 minutes at a low bubble until it coats a spoon. Off heat, stir in cheese in three additions to avoid clumping.
Rest 2 minutes before serving so the sauce settles. Broccoli florets go in during the last 3 minutes of cooking; overcooking turns them army green. For a dairy-free version, replace cream with full-fat coconut milk and cheese with 3 tbsp nutritional yeast plus 2 tbsp cashew cream.
For higher-protein, fold in 6 oz shredded rotisserie chicken or 4 oz cooked bacon crumbles for another 20g protein per serving. For a vegetarian keto boost, add 4 oz sauteed mushrooms and a poached egg on top of each portion.
Storage and Reheating
Refrigerate up to 3 days in a sealed container. Reheat over low heat in a saucepan with 2 tbsp extra cream or stock to loosen the sauce. Microwave reheating separates the fat and turns the texture grainy. Not recommended for freezing; the cream sauce breaks on thaw.
