It’s quick, cozy, and perfect as a side or vegetarian main, ready in just 25 minutes!
1 medium head cauliflower, cut into small florets
250 g / 8 oz mushrooms (button, cremini, or Swiss brown), thickly sliced
3 tbsp butter, divided
1 tbsp olive oil
4 cloves garlic, minced
1 small shallot (or ½ small onion), finely chopped (optional)
¼ tsp red pepper flakes (optional, for a little heat)
Salt and pepper, to taste
1 tbsp fresh parsley or thyme, chopped
1–2 tsp lemon juice, to finish
Prep the vegetables: Cut cauliflower into bite-size florets. Slice mushrooms thickly and pat them dry with paper towels.
Start aromatics: Heat 1 tbsp butter and 1 tbsp olive oil in a large skillet over medium heat. Add shallot and cook 1–2 minutes until soft. Add garlic and red pepper flakes, cooking just 30 seconds until fragrant.
Brown cauliflower: Add cauliflower florets in a single layer. Let them sear without stirring for 3–4 minutes to develop golden edges, then stir and cook another 3 minutes.
Cook mushrooms: Add mushrooms and another tablespoon of butter. Stir occasionally for 5–6 minutes until mushrooms release their moisture and turn golden brown.
Season and finish: Season well with salt and pepper. Add the remaining tablespoon of butter and toss until everything is coated and glossy.
Add herbs and lemon: Remove from heat, stir through parsley, and add a quick squeeze of lemon juice. Serve hot straight from the skillet.
Mushroom type: Any variety works, button and cremini give the best texture.
Don’t crowd the pan: Overcrowding makes the veggies steam instead of brown. Use a big skillet!
Vegan option: Swap butter for vegan butter or olive oil.
Make it a meal: Add cooked chicken, shrimp, or toss with pasta.
Storage: Refrigerate in an airtight container up to 3 days. Reheat gently in a skillet or microwave.
