2 carrots, peeled and diced (about 1 cup)
1 red bell pepper, diced

2 tsp dried thyme (or 1 tbsp fresh)
1 tsp smoked paprika
Salt & black pepper to taste (about 1 tsp each)

How To Make Garlic Cauliflower Mushroom Skillet

1. Chop the Veggies

Start by washing and preparing all your vegetables. Remove the leaves from the cauliflower and cut the head into small, even florets so they cook uniformly. Slice the mushrooms into similar-sized pieces to ensure they cook evenly. Dice the onion, carrots, and red bell pepper, and finally, mince the garlic finely so it releases its flavor fully into the dish. Having all your ingredients prepped before you start cooking will make the process smooth and stress-free.

2. Heat the Skillet

Grab your largest skillet—trust me, this recipe makes a generous portion! Place it over medium heat and add 2 tablespoons of olive oil. Let it warm for about a minute until it shimmers slightly. Swirl the oil around the pan so that the bottom is evenly coated. This will prevent any sticking and help your veggies get that beautiful golden color.

3. Sauté the Cauliflower

Toss in the cauliflower florets and stir to coat them in the warm oil. Cook them for 5–7 minutes, stirring occasionally. You want the cauliflower to start softening while also getting a little bit of color. If you love crispy bits, let them sit undisturbed for a minute or two before stirring.

4. Add Mushrooms, Onion, Carrots, and Bell Pepper

Once the cauliflower has started to turn golden, add the mushrooms, diced onion, carrots, and bell pepper. Stir well so everything is evenly distributed. The mushrooms will release some liquid, which helps steam the cauliflower a bit more.

5. Add the Garlic

After about 2 minutes of cooking the mixed vegetables, sprinkle in the minced garlic. Stir everything together, and let the garlic cook for 3–5 minutes, releasing that incredible aroma. Be careful not to let the garlic burn—keep the heat at medium and stir occasionally.

6. Season and Add Flavor

Sprinkle in the dried thyme, smoked paprika, salt, black pepper, and red pepper flakes (if using). Drizzle the balsamic vinegar over the top for a tangy depth of flavor. Stir everything thoroughly so the spices coat every bite.

7. Optional Add-ins

If you’re adding peas or cheese, now’s the time! Stir in frozen peas and let them heat through for 2 minutes. For a cheesy twist, sprinkle shredded Parmesan or vegan cheese over the skillet before serving—it melts beautifully into the warm veggies.

8. Serve and Enjoy

Remove the skillet from heat. Top with fresh parsley or basil for a bright finish. Serve as a main dish or pair with rice, pasta, or your favorite protein. Leftovers keep wonderfully and taste even better the next day!
