We always keep bags of frozen veggies in the freezer, cheap and convenient for adding vegetables to dinner. Instead of microwaving, we roast them in the oven whenever possible, like How to Roast Frozen Green Beans.
Oven roasting enhances the texture and flavor of this versatile vegetable. We enjoy it this way often. Roasting frozen cauliflower brings out its sweetness and creates a crispy texture.
It's a flavorful side dish that complements various mains. I appreciate that I can cook it alongside my main dish, both finishing full of flavor. We love pairing it with Stuffed Chicken Roll Ups, Crispy Sour Cream and Onion Chicken, and Stuffed Chicken Legs.

💛 Why You'll Love This Recipe
- Big flavor, minimal effort: The broth adds flavor while the cauliflower roasts, keeping it from tasting flat or bland.
- Ridiculously easy: Toss everything on a sheet pan and bake. No extra steps, no fuss. Roasted veggies like Roasted Brussel Sprouts and Carrots or Garlic Parmesan Roasted Green Beans require extra steps, making this recipe more simple by comparison.
- A better way to use frozen veggies: If you're tired of plain steamed vegetables, this is an easy upgrade that still fits busy nights.
🛒 Ingredients
Frozen cauliflower- For this recipe, grab a bag of frozen cauliflower. Any brand will work. You want the bag to be about 12 ounces in size.
Chicken broth- This is an optional ingredient, but it's one that I have discovered truly makes cauliflower taste incredible.

💰 Budget-Friendly Tips
Use frozen cauliflower: Frozen is usually cheaper than fresh and lasts longer, so there's no waste.
Swap the broth: Use whatever broth you already have on hand. Vegetable broth works just as well, or even a splash of water in a pinch.
Season from the pantry: Simple spices keep this recipe affordable while still adding plenty of flavor.
🥄 Instructions for Roasted Frozen Cauliflower
Step 1: Preheat your oven to 350 degrees F or 450 degrees F, and grease a baking sheet.
Step 2: Open the bag of frozen cauliflower and place them onto the sheet.
Step 3: Drizzle the olive oil over the cauliflower and then follow it up by sprinkling the spices over the top. Drizzle the chicken broth as well.
Step 4: Use clean hands to toss the veggies around in the mixture until all veggies are well coated.

Step 6: Remove from oven and serve warm with your meal.
👩🏻🍳 Expert Tips
- Flexible oven temps: Roast at 450°F for faster, crispier results or 350°F if you already have something else in the oven. Both work great.
- No thawing needed: Frozen cauliflower goes straight from the bag to the pan. Just break up any large clumps so everything cooks evenly.
- Easy cleanup: Everything cooks on one sheet. Lining the pan with parchment or foil makes cleanup even quicker.
❄️ Storage and Reheating
Storage: Store leftover roasted frozen cauliflower in an airtight container in the refrigerator for up to 3 days.
Reheating: Reheat in a 400°F oven for 5-8 minutes to help restore crisp edges, or microwave briefly if you're short on time.

❓ Recipe FAQs
Absolutely! We like to double the recipe below because we just can't seem to get enough of it. I mean, how often do you get kids to WANT to eat extra veggies? Doubling or tripling the recipe will not increase bake time as long as the cauliflower is nicely spaced out and not piled up too much.
You can keep the leftover cooked frozen cauliflower in an airtight container in the fridge for up to 3 days. Just reheat before eating.
If you overcrowd the baking sheet with frozen cauliflower, the moisture that they will leave behind as they thaw and cook will be absorbed by one another. This means that they can become mushy if too much moisture is absorbed. To avoid this, limit the additional liquid by not overcrowding the pan.
