Cauliflower risotto has a credibility problem. Every version I’ve tried in restaurants is either watery or so aggressively seasoned you can’t tell what you’re eating. This one avoids both. The cauliflower gets riced finely and cooked down in broth until it’s genuinely creamy, not just soft and wet. The porcini mushrooms go in roasted, not raw, which keeps them from turning the whole dish into a soggy mess. White wine vinegar at the end cuts through the starch and makes it taste finished. It’s not a perfect substitute for arborio risotto and I wouldn’t claim otherwise. But as a lighter, faster dinner that doesn’t leave you half-asleep by 8pm, it does the job.
How to Make Cauliflower Risotto with Roasted Mushrooms
Roast the mushrooms separately
Porcini slice thin and crisp up fast at 350°F. Don’t crowd them on the baking sheet or they steam instead of roast. Twelve minutes is usually enough; you want edges that are slightly golden, not limp.
Ricing the cauliflower
A food processor makes quick work of the florets. Pulse in short bursts rather than running it continuously; you want small, even grains, not cauliflower paste. If you’re chopping by hand, go fine. 
Finishing the dish
Add the broth gradually and stir regularly while the cauliflower absorbs it. The white wine vinegar goes in at the very end. Don’t skip it; it’s doing more work than it looks like.

Description
Creamy cauliflower risotto gets an earthy boost from roasted porcini mushrooms. A simple, elegant weeknight meal.
Ingredients
- 8 oz (227 g) Porcini mushrooms, sliced
- salt and pepper
- olive or coconut oil cooking spray
- 1 medium yellow onion, thinly diced
- 2 tsp minced garlic
- 1 medium head cauliflower, cut into florets
- 2 cups (473 ml) low sodium vegetable broth
- 2 tsp white wine vinegar
Instructions
For the roasted mushrooms
- Preheat oven to 350°F (177°C). Grease or line a baking sheet with foil.
- Spread sliced mushrooms on the baking sheet, spray with cooking spray, sprinkle with salt, and toss until evenly distributed.
- Bake at 350°F (177°C) for 10-12 minutes, or until golden and slightly crispy.
- Set aside.
For the risotto
- Heat a large skillet over medium-high heat.
- Add thinly diced onion and cook, stirring often, until translucent (3-4 minutes).
- Add minced garlic and cook for 2 minutes, or until golden.
- Process cauliflower florets in a food processor until it resembles rice (2-3 minutes).
- Add cauliflower rice to the skillet and stir for 1 minute, until combined.
- Heat vegetable broth to a gentle simmer.
- Add ¼ cup of simmering broth to the skillet and cook, stirring constantly, until incorporated. Repeat until ½ cup of broth remains.
- Stir in white wine vinegar to taste, then stir in the remaining broth.
- Let the risotto sit on the stove over low heat to allow flavors to mingle and caramelize (optional).
- Season with salt and pepper to taste.
- Top with roasted mushrooms.
Notes
- For a richer flavor, use homemade vegetable broth instead of store-bought.
- If you don’t have a food processor, finely chop the cauliflower by hand, but be aware that cooking time may be longer.
- Leftover risotto can be stored in the refrigerator for up to 3 days and reheated gently on the stovetop or in the microwave.

Frequently Asked Questions
Can I use a different type of mushroom?
Cremini, shiitake, or oyster mushrooms all roast well. Porcini have a stronger flavor, so if substituting, consider adding a pinch of dried porcini powder for depth.
How do I get the cauliflower to a rice-like texture?
Pulse the florets in a food processor in short bursts until they resemble coarse grains. Don’t over-process or you’ll end up with a puree instead of a risotto texture.
Can I make this ahead?
The cauliflower base reheats well in a skillet with a bit of extra broth. Roast the mushrooms fresh or reheat them in the oven to restore their crispness.
