This dish blends zucchini, yellow squash, cauliflower, red bell pepper, and red onion tossed in olive oil and seasoned with thyme, rosemary, garlic powder, salt, and pepper. It’s roasted to tender perfection, then topped with melted Parmesan and mozzarella for a hearty, comforting low-carb side. Ideal for keto and gluten-free diets, it offers a flavorful vegetable medley suitable for cozy dinners, easily paired with grilled meats or served as a satisfying vegetarian option.

The winter our old fireplace mantle finally gave up the ghost, we spent months eating dinner by the space heater in the corner of the kitchen. This roasted vegetable medley became our weekly ritual, something about the way the rosemary perfumed the whole house made those chilly evenings feel deliberate instead of just cold.

My sister-in-law stayed over during a particularly bleak February and requested this three nights in a row. She said it reminded her of Sunday suppers at her grandmothers house, though honestly I think she just loved how the kitchen smelled like an Italian restaurant for hours afterward.

Ingredients

  • 1 medium zucchini, sliced: Cut these about 1/2 inch thick so they do not turn to mush in the oven
  • 1 medium yellow squash, sliced: The yellow variety brings a slightly sweeter flavor that balances the cauliflower
  • 1 small head cauliflower, cut into florets: Keep the pieces relatively uniform for even roasting
  • 1 red bell pepper, diced: Red peppers become almost candy-like when roasted, adding natural sweetness
  • 1/2 small red onion, sliced: Red onion mellows out beautifully and provides pretty color contrast
  • 3 tbsp olive oil: This helps the seasonings stick and promotes that gorgeous browning
  • 1/3 cup grated Parmesan cheese: The salty, umami punch that ties everything together
  • 1/3 cup shredded mozzarella cheese: Creates those irresistible melted cheese pockets
  • 1 tsp dried thyme: Earthy and subtle, thyme plays well without overpowering
  • 1 tsp dried rosemary: This is the fireside fragrance that makes the whole house feel cozy
  • 1/2 tsp garlic powder: Distributes evenly throughout the dish unlike fresh garlic
  • Salt and black pepper, to taste: Do not be shy here, roasted vegetables can handle plenty of seasoning

Instructions

Get your oven ready:
Preheat to 400°F and line a baking sheet with parchment paper for the easiest cleanup imaginable.
Coat the vegetables:
In a large bowl, toss all the vegetables with olive oil, thyme, rosemary, garlic powder, salt, and pepper until every piece glistens.
Arrange for roasting:
Spread the vegetables in a single layer on your prepared baking sheet, giving them room to breathe.
First roast:
Roast for 20 minutes, stirring halfway through so nothing burns and everything gets those golden edges.
Add the cheese:

Serve it up:
Bring the whole pan to the table, maybe with some extra herbs sprinkled on top if you are feeling fancy.

Now we have a proper fireplace again, but this dish remains a winter staple. Something about vegetables roasted until they are tender and bubbling with cheese just makes the world feel softer, no matter what is happening outside.

Making It Your Own

Broccoli florets work beautifully here, and mushrooms add a meaty texture that makes this feel more substantial. Last week I threw in some asparagus spears during the last 10 minutes and they were perfect, still snappy with those charred tips everyone loves.

The Science of Roasting

High heat causes the natural sugars in vegetables to caramelize, creating deep flavors that simply do not happen with other cooking methods. The moisture evaporates and concentrates everything, which is why roasted vegetables taste so much more intense than steamed ones.

Serving Suggestions

This pairs alongside any grilled meat, but honestly I have eaten it as a main dish more times than I care to admit, especially with a fried egg on top. The leftovers reheat surprisingly well in a 350°F oven for about 10 minutes.

  • Try crumbling some cooked bacon over the top before serving
  • A drizzle of balsamic glaze right before serving adds brightness
  • Extra red pepper flakes if you want a little heat
