- Sugar-free: Flavor comes from butter, garlic, and herbs.

Key element — don’t crowd the pan
Mushrooms and cauliflower steam if they sit on top of each other. Give them space so the edges brown and the butter stays nutty, not watery.
Ingredients
Skillet (4 servings)
- 1 medium head cauliflower, cut into florets (about 6 cups)
- 12 oz (340g) mushrooms, halved or sliced
- 3 Tbsp butter
- 1 Tbsp olive oil
- 4 cloves garlic, minced
- ⅓ cup grated Parmesan
- ½ tsp salt
- ½ tsp black pepper
- ¼ tsp paprika or Italian seasoning
- 2 Tbsp chopped parsley
- 1 Tbsp lemon juice (optional)
Swaps
- Higher protein: Add extra Parmesan or toss in leftover shredded chicken.
- Dairy-free: Use ghee or olive oil and skip the cheese, or use a dairy-free hard cheese.
- Spicy: Add red pepper flakes with the garlic.
- Oven: Roast at 425°F for 20–22 minutes, then toss with garlic butter.
Instructions
| 1 | Heat the pan. Warm butter and oil in a large skillet over medium-high heat. |
| 2 | Brown the vegetables. Add cauliflower and mushrooms in a single layer. Cook 8–10 minutes, stirring only once or twice, until the edges are golden. |
| 3 | Add garlic. Lower the heat. Stir in garlic, salt, pepper, and paprika for 30–45 seconds so the garlic doesn’t burn. |
| 4 | Finish. Toss with Parmesan, parsley, and lemon juice. Taste and serve hot. |
Pro tips
- Dry the mushrooms after rinsing or they won’t brown.
- Cut florets similar in size so they cook evenly.
- If the pan looks dry, add another teaspoon of butter instead of water.
- A splash of lemon at the end keeps the dish from tasting heavy.
- Leftovers reheat well in a hot skillet, not the microwave.
