Roasting brussels sprouts is quite easy, but for busy families, time can be an issue. Life gets hectic, and sometimes we struggle to get a healthy dinner ready on the table, let alone think of the sides! I also understand that not everyone can afford to buy fresh brussels sprouts, and cook them in time while they’re fresh, so this method uses frozen Brussels sprouts that you can always find in your freezer. In this recipe, I will show you how to make CRISPY brussels sprouts that are tender from the inside. But I have to be honest with you, they’re not 100% the same as roasting fresh brussels sprouts. But hey, an easy and healthy side dish that you can make using that frozen brussels sprouts bag that you have in your freezer? Count me in! This method is very similar to Roasted Cauliflower, it’s a great way of cooking frozen veggies while keeping their nutritional value and flavor intact.

How to Roast Frozen Brussels Sprouts

The Ingredients

Complete list of ingredients and amounts can be found in the recipe card below.

Frozen brussels sprouts – straight from the bag! I always keep a bag or 2 in my freezer.Olive oil – don’t skip the oil, as it’s what will make your Brussels sprouts crispy and good! It also adds a lot of flavor especially if you’re using olive oil. You can also use canola, sunflower, or avocado oil.Seasoning – I usually season with just salt and pepper, but feel free to add your favorite seasonings! Try my homemade ranch seasoning, everything bagel seasoning, or Italian seasoning.Parmesan cheese – optional, and sprinkled at the end. Adds so much flavor!

Instructions

Recipe Variations

This is a basic recipe, it’s plain but it’s also good! However, if you like more flavor, then feel free to add your favorite seasonings, or any add-ons like maple syrup and bacon, garlic, Italian seasoning, balsamic vinegar, or chili flakes.

Storing Tips

Store leftover roasted brussels sprouts in an airtight container in the fridge for up to 3 days. I don’t recommend freezing them as they will become too soft and mushy. Reheat in the oven at 350°F/180°C until warmed through.

Baking sheet – this is the one that I use and love! It’s a quarter sheet, but if you’re doubling the recipe then use a half sheet pan. Turner – what you see in the images is a fish turner, but I use it for everything. It’s large and great to use! © Little Sunny Kitchen
