Equipment

  • Large skillet or sauté pan
  • Knife + cutting board
  • Wooden spoon or spatula
  • Measuring spoons
  • Lid (optional, for steaming step)

Ingredients
  

Core:

  • 1 medium head of cauliflower, cut into florets
  • 8 oz cremini or button mushrooms, thickly sliced
  • 3–4 cloves garlic, minced
  • 1 small shallot or ½ yellow onion, finely diced
  • 2 tbsp olive oil
  • 1 tbsp butter (or plant-based butter for vegan)

Flavor boosters:

  • ¼ cup vegetable or chicken broth (or dry white wine)
  • ½ tsp salt, to taste
  • ¼ tsp black pepper
  • ½ tsp fresh or dried thyme (or parsley)
  • Pinch of red pepper flakes (optional)
  • 1 tsp lemon juice or zest (optional)

Optional Add-ins:

  • 2 tbsp grated Parmesan or nutritional yeast
  • ½ cup chickpeas, cooked (for protein boost)
  • ½ cup zucchini or bell pepper, chopped

Instructions
 

Prep ingredients:

  • Cut cauliflower into uniform florets and slice mushrooms. Mince garlic and dice shallots/onion.

Sauté aromatics:

  • Heat olive oil and butter in a large skillet over medium heat. Add shallots/onion and sauté for 2–3 minutes until soft and lightly golden.

Cook mushrooms:

  • Add sliced mushrooms in a single layer. Let them sit undisturbed for 4–5 minutes until browned, then stir and cook for another 3–4 minutes.

Add cauliflower:

  • Stir in cauliflower florets. Cook for 7–8 minutes, stirring occasionally to let edges brown and caramelize. Add more oil if needed.

Deglaze & steam:

  • Pour in broth or wine. Stir to deglaze the pan. Cover loosely and let steam for 2–3 minutes until cauliflower is tender.

Finish with garlic & herbs:

  • Uncover, add garlic and herbs. Sauté for 30–60 seconds until fragrant. Season with salt, pepper, and optional chili flakes or lemon.

Serve:

  • Garnish with Parmesan, nutritional yeast, or herbs. Serve warm as a side or light main.

Notes

  • Vegan-friendly: Use plant-based butter and veggie broth.
  • Don’t overcrowd the skillet—work in batches for best browning.
  • Add garlic at the end to prevent bitterness.
  • Storage: Refrigerate up to 5 days or freeze for 3 months. Reheat in a skillet with a splash of broth or water.
  • Perfect pairings: Serve with grains like quinoa or rice, or alongside grilled proteins for a balanced meal.
