- 3 cloves garlic, minced: Offers a fragrant punch that elevates the skillet’s overall aroma.
- ¼ cup unsalted butter (or vegan butter): Brings creaminess and helps meld the flavors together beautifully.
- 2 tbsp olive oil: Ensures perfect sautéing with a subtle fruity undertone.
- ¼ cup low-sodium vegetable broth: Keeps the vegetables moist while adding savory notes without overpowering.
- 1 tsp Italian seasoning: Infuses the skillet with herbal nuances of oregano, thyme, and basil.
- Salt and freshly ground black pepper, to taste: Essential seasonings that highlight each ingredient’s natural taste.

How to Make Cauliflower Mushroom Skillet Recipe
Step 1: Heat the fats for a perfect base
Start by warming the olive oil and butter together in a large skillet over medium-low heat. This combination not only prevents the butter from burning but also creates a rich, luscious base that your veggies will love to cook in.
Step 2: Caramelize the onions until golden
Add the sliced onion and sauté it gently for about 4 to 5 minutes until it turns golden brown and sweetly fragrant. This caramelization is key to layering flavor and brings a wonderful sweetness that balances the earthiness of the mushrooms.
Step 3: Add cauliflower, mushrooms, and seasonings
Next, toss in the cauliflower florets and mushrooms. Sprinkle in the Italian seasoning, salt, pepper, and pour the vegetable broth into the skillet. This combination infuses the vegetables with savory, herbal notes while keeping everything moist as they cook.
Step 4: Sauté until browned and tender
Increase the heat to medium-high and cook the mixture for 8 to 10 minutes. Stir occasionally until the cauliflower and mushrooms develop a beautiful golden-brown color and are tender but still hold a slight crunch—this gives the dish a perfect balance of texture.
Step 5: Add garlic and finish cooking
Stir in the minced garlic and cook it for just 30 seconds, enough to release its aroma but not so long that it turns bitter. Garlic adds a wonderful finishing layer of subtle warmth and depth right before taking the skillet off the heat.
Step 6: Adjust seasoning and remove from heat
Give everything a taste and tweak the salt, pepper, or red pepper flakes if you want a bit more spice. Once it tastes just right, remove the skillet from the stove—you’re almost ready to enjoy!
Step 7: Garnish before serving
Sprinkle freshly chopped parsley and a dash of red pepper flakes (if using) over the dish to add a pop of color and a hint of brightness that perfectly rounds out this hearty skillet creation.
How to Serve Cauliflower Mushroom Skillet Recipe
Garnishes
Fresh parsley not only enhances the visual appeal but adds a fresh, herbal brightness that cuts through the richness of the butter and mushrooms. For an extra touch, sprinkle some lemon zest or a squeeze of lemon juice to brighten up the flavors even more.
Side Dishes
This skillet pairs wonderfully with a simple green salad for a light meal or a side of quinoa or brown rice to turn it into a more filling dinner. Crusty bread works beautifully too, perfect for soaking up every last bit of buttery sauce.
Creative Ways to Present
For a colorful twist, serve this skillet atop creamy polenta or toss in some toasted pine nuts or slivered almonds for a pleasant crunch. Drizzling a bit of balsamic glaze over the top just before serving adds a sweet-tangy contrast that impresses every time.
Make Ahead and Storage
Storing Leftovers
Once cooled, transfer your cauliflower mushroom skillet into an airtight container and keep it in the refrigerator. It’s best consumed within 3 to 4 days to enjoy its fresh flavors and texture.
Freezing
This dish freezes surprisingly well. Portion it out into freezer-safe containers or bags, and it can be frozen for up to 2 months. When ready to enjoy, thaw overnight in the fridge for best results.
Reheating
To reheat, gently warm the skillet over medium heat on the stove or microwave it in short bursts to avoid overcooking the vegetables. Adding a splash of vegetable broth or water while reheating helps maintain its moisture and keeps those wonderful flavors vibrant.
FAQs
Can I use different mushrooms in this Cauliflower Mushroom Skillet Recipe?
Absolutely! While cremini mushrooms offer a great earthy flavor and firm texture, you can experiment with shiitake, button, or portobello mushrooms depending on your preference and availability. Just adjust cooking times slightly for size variation.

How spicy is this dish with red pepper flakes?
The red pepper flakes provide just a gentle warmth—not overpowering but enough to lift the flavors and add a little kick. Feel free to adjust or omit as per your heat tolerance.
What’s the best size skillet to use for this recipe?
A large 10 to 12-inch skillet works perfectly, giving enough room for the vegetables to brown nicely without overcrowding, which helps achieve the best texture and flavor development.
