Ingredients

(Here's a tip: Check out the full list of ingredients and measurements in the recipe card below.)

2 tablespoon olive oil
2 tablespoon butter
1 small head cauliflower, cut into florets
8 oz mushrooms, sliced
4 cloves garlic, minced
½ teaspoon smoked paprika
½ teaspoon Italian seasoning
Salt & black pepper, to taste
1 tablespoon lemon juice
¼ cup Parmesan cheese (optional)
Fresh parsley, for garnish

Directions

I heat a large skillet over medium heat and add the olive oil and butter.
Then I toss in the cauliflower florets and cook them for about 5–6 minutes until they begin to turn golden.
Next, I add the mushrooms and continue sautéing everything together for another 4–5 minutes until the mushrooms are tender.
I stir in the garlic, smoked paprika, Italian seasoning, salt, and black pepper, letting it all cook for an additional 2 minutes until it smells amazing.
To finish, I drizzle lemon juice over the mixture, sprinkle with Parmesan if I'm using it, and garnish with fresh parsley before serving it hot.

Variations

When I want a bit of crunch, I like to top the dish with toasted almonds or pine nuts. If I’m craving a kick, a pinch of red pepper flakes does the trick. For a cheesier finish, I sometimes stir in shredded mozzarella just before serving—it melts beautifully and adds a creamy texture.

storage/reheating

I store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, I simply warm the dish in a skillet over medium heat, adding a splash of water or a little butter to keep it from drying out. The microwave works too, but I prefer the skillet for best texture.

FAQs

How can I make this dish vegan?

I swap out the butter for more olive oil or a plant-based butter, and I skip the Parmesan or use a vegan cheese alternative.

Can I use frozen cauliflower?

Yes, but I prefer to thaw and pat it dry first. It helps prevent excess moisture from watering down the dish.

What type of mushrooms work best?

I usually go with cremini or white button mushrooms, but shiitake or portobello also work beautifully for a deeper flavor.

Can I make this ahead of time?

Yes, I often prep the cauliflower and mushrooms in advance. I can cook the dish a few hours ahead and reheat before serving.

Is this recipe keto-friendly?

Absolutely. With only around 7g of net carbs per serving, it fits well into a keto or low-carb lifestyle.
