They come packed with high levels of vitamin C and vitamin K, with a single serving providing well over the recommended daily amount of these essential nutrients. 

In addition to vitamins, they are rich in fiber, which aids in digestion, and contain potent compounds that may help reduce the risk of chronic diseases such as cancers and heart disease.

How Long To Bake Brussel Sprouts At 350?

To perfectly bake fresh Brussels sprouts at 350°F, they typically need about 30 to 35 minutes in the preheated oven.

It’s essential, however, to keep an eye on them and shake the baking sheet or stir the sprouts halfway through the cooking time to ensure they roast evenly. 

However, how long to bake brussel sprouts at 350 depends on the status of the food.

If you use fresh Brussels sprouts, the baking time may be less than the one of frozen Brussels sprouts.

1. Fresh Brussel Sprouts

When cooking with fresh Brussels sprouts, it’s crucial to bake them until they are fork-tender and the exterior leaves have turned a crispy, golden-brown color.

Start by spreading the sprouts in a single layer on a baking sheet, giving them plenty of space to ensure even roasting. 

It will take 30-35 minutes to bake fresh Brussels sprouts at 350°F, checking at the 15-minute mark to stir or shake the pan for uniform cooking.

Remember, the size of your sprouts will slightly alter the cooking time – smaller sprouts may take less time, whereas larger ones could require a few extra minutes. 

2. Frozen Brussel Sprouts

Using frozen Brussels sprouts can be a convenient option, especially when the fresh variety is out of season.

Before baking, there is no need to thaw the sprouts, they can go straight from the freezer to the oven but they may not become as crisp as fresh ones due to excess moisture content.

Bake the frozen Brussels sprouts at 350°F in the oven for about 45-50 minutes.

Since they’re frozen, they might require a longer time in the oven compared to fresh sprouts.

Halfway through baking, give the sprouts a good stir to promote even cooking and browning.

If you use frozen Brussels sprouts, you can try baking sprouts at 350 with an air fryer to save time.

It will take around 15-20 minutes if preheated in advance.

How To Choose Brussels Sprouts?

Selecting the right Brussels sprouts is the first step to ensure a delicious outcome when baking.

Look for bright green heads that are firm and heavy for their size, indicating freshness and moisture content. 

The leaves should be tightly packed, crisp, and free from yellowing or blemishes.

Smaller sprouts are typically sweeter and more tender, while larger ones can be more cabbage-like in flavor. 

If possible, try to pick Brussels sprouts that are similar in size for even cooking.

Avoid sprouts that have a pungent smell or show signs of wilting, as these are indications that they are past their prime. 

How To Prepare Brussels Sprouts For Baking?

Preparing Brussels sprouts for baking is straightforward and sets the stage for a delicious side dish:

Begin by rinsing the sprouts in cold water to remove any dirt or debris.

Trim off the stem ends and remove any yellow or damaged outer leaves.

If the sprouts are particularly large, cut them in half to promote even roasting and ensure each piece caramelizes nicely.

Optionally, you can score the bottoms with a shallow X to ensure the heat penetrates the core. 

Finally, toss the prepared sprouts with a bit of olive oil – this will help them develop a golden-brown exterior – and season with salt and pepper before they go into the oven.

Alternative Ways To Cook Brussel Sprouts

1. Sautéing Brussels Sprouts

Sautéing Brussels sprouts quickly cooks them to tender-crisp perfection.

Start by heating a couple of tablespoons of oil or butter in a large pan over medium-high heat. 

Cut the sprouts in half and place them cut-side down in the pan, cooking until they are nicely browned.

Then, flip the sprouts, lower the heat to medium, cover the pan, and continue cooking until they are tender.

Season with salt, pepper, and your choice of herbs or spices for a flavorful finish. Then, you can enjoy them.

2. Steaming Brussels Sprouts

For a healthier preparation method, steaming Brussels sprouts preserves most of their nutrients and is quite simple.

Trim and clean the sprouts as usual, then place them in a steamer basket over boiling water. 

Cover them with a lid and let them steam until they’re just tender, which usually takes about 6 to 8 minutes depending on their size.

Once done, you can toss them with a dab of butter or a sprinkle of grated cheese for added flavor.

3. Grilling Brussels Sprouts

To add a smoky flavor, grilling Brussels sprouts is an excellent option.

Prepare the sprouts by cutting them in half and coating them with oil and your favorite seasonings.

If they’re small, use a grill basket to prevent them from falling through the grates.

Place them on a preheated grill over medium heat and cook for about 8 to 10 minutes, turning occasionally, until they are charred to your liking and tender inside.

4. Braising Brussels Sprouts

Braising is a technique that involves cooking Brussels sprouts slowly in a small amount of liquid.

This method is perfect for developing deep flavors. 

Begin by browning the sprouts in a skillet with some butter or oil.

Then, add a cup of broth, wine, or a mix of both, and bring to a simmer.

Cover and let the sprouts cook for about 20 minutes or until tender.

The liquid will reduce, creating a rich glaze that coats the sprouts beautifully.

5. Roasting Brussels Sprouts with Other Flavors

Combining Brussels sprouts with other ingredients while roasting can create an array of flavors.

Toss the cleaned and trimmed sprouts with diced bacon, sliced onions, or crushed garlic before roasting them.

Drizzle with balsamic vinegar or sprinkle with Parmesan cheese in the last few minutes of baking for a savory twist.

What We Should Avoid When Baking Brussels Sprouts?

When baking Brussels sprouts, it’s important to avoid overcrowding the pan.

If the sprouts are too close together, they will steam rather than roast, preventing them from achieving the desired caramelization. 

Additionally, be careful not to over-season.

While spices can enhance the flavor, too much can overpower the natural taste of the sprouts and even make the sprouts burnt when baking.

Lastly, steer clear of using excessive oil which can make them soggy instead of crispy.

It’s also essential to avoid baking at too high a temperature; this can cause the outer leaves to burn before the inside is tender.

How To Store Brussels Sprouts?

Brussels sprouts are best stored in the refrigerator to maintain their freshness.

When you bring them home, don’t wash them right away, place the unwashed Brussels sprouts in a plastic bag or a container with a lid or tissue and store them in the vegetable crisper of your refrigerator. 

If you have cooked Brussels sprouts leftovers, store them in an airtight container.

Put them in the cool refrigerator compartment and keep them for 3-4 days. 

For longer storage, Brussels sprouts can be blanched and then frozen.

To do this, boil them for a few minutes, then plunge into ice water to halt the cooking process. 

Dry completely and freeze in a single layer on a baking sheet before transferring to a freezer bag or container.

They can be kept frozen for up to 12 months.


In conclusion, Brussels sprouts are a versatile vegetable that can be enjoyed year-round and prepared in a multitude of tasty ways.

Whether roasted, sautéed, steamed, grilled, or braised, they offer both health benefits and palate-pleasing flavors.

By following the simple techniques outlined in this guide, you can achieve perfect results that bring out the natural deliciousness of Brussels sprouts.

Always remember to store them correctly, season them judiciously, and cook them to your preferred tender-crispness to savor their full potential.
