How healthy are Brussels sprouts for you?
Brussels sprouts are high in antioxidants, vitamins, and minerals, as well as high in fiber.
The perfect vegetable to add to your diet.
How do you know when Brussels sprouts are ripe?
The season for Brussels sprouts on the Northern Hemisphere is from October and lasts through March. Of course, with the hot houses, our grocery stores always offer them.
They should be firm and a bright green color. You want them free of buds that start turning yellow and begin to open.
Once you see the leaves turn yellow, brown, or wilted and smell like cabbage, they are too old and should not be eaten.
What is Old-Style Mustard?
Mustard seeds are blended with vinegar and white wine into a rich, fruity-scented paste.
The old-style mustard is milder than your regular mustard.
Do not substitute with regular mustard with this recipe, as it will not be the same flavor.
Here are a few helpful tips for the ingredients needed to make these delicious oven-roasted Brussels sprouts
This is a quick introduction. Please read the recipe for complete instructions.
Brussels Sprouts: Ensure they are all the same size for even roasting. Check that the nubby end is clear and not dark-spotted. The other leaves are tightly close to each other.
Olive oil: A light olive oil will not interfere with the flavor of the Brussels sprouts. Bertolli has been my cooking life-long favorite.
Old Style grain mustard: Classic Dijon mustard is characterized by its grainy texture.
Mayonnaise: if you can make homemade it, it is the best. However, Kraft makes a pretty good one, and it is easily accessible worldwide.
Parsley: Optional but adds a nice layer of flavor to this dish.
I only recommend what I use and love.
Cutting board: I always use wood as they are gentle on my knife blades.
Chef’s knife: a must in every kitchen. The sprouts are a bit tough to cut thru, and a sharp knife will facilitate the slicing.
Mixing bowl and spatula: Used twice with this recipe. Once to prepare the Brussels sprouts before roasting, and the second time to prepare the sauce and mix them soon after coming out of the oven.
Baking sheet: use a large one so your sprouts will have room to be spread out.
Serving dish: A lovely dish is always welcome to the table.
Roasting tips to consistently achieve excellent oven-roasted Brussels sprouts.
A few tips and tricks will ensure your roasted Brussels sprouts turn out perfectly every time.
Start by choosing your Brussels bright green sprouts with the outer leaves intact and tight to each other. Firm when you gently squeeze them. Having them all the same size is beneficial for even roasting.
Trim the nubby ends and slice in half from the flat base through the top. You want that flat edge that will bake flush to the pan and caramelize.
Do not remove the core. It holds your leaves together, and during the roasting process, it will soften out and give you a great flavor.
Do not overcrowd the baking sheet, or they will produce steam when they roast and will never crisp up to your liking. If making them for a crowd, use two baking sheets. You will thank me for it later.
Bake at a high temperature to get crispy with golden edges, but not too high that the olive oil burns the baking sheet and creates that unpleasant bitter flavor.
But most importantly, do not disturb them when they are roasting.
Halved Brussels sprouts, when placed flat side down against the pan, will steam the inside, making them perfectly golden and crispy on the outside and perfectly tender on the inside.
And step-by-step to make these delicious roasted Brussels sprouts with mustard.
This recipe is very quickly achieved.
- Wash the Brussels sprouts, dry them, slice them lengthwise, and place them in a bowl.
- Add olive oil to them and ensure that each piece is nicely covered.
- Transfer the Brussels sprouts to a large baking sheet and turn with all cut flat side facing the baking sheet.
- In the oven, they go.
Meanwhile, prepare the sauce by whisking together the mayonnaise and the old-style grain mustard.
- Once the Brussels sprouts are golden and ready, remove them from the oven and add them to the prepared mayo-mustard sauce.
- Season with salt and pepper, mix well.
- Transfer to a serving dish, sprinkle the finely chopped parsley, and enjoy.
What can you serve with your oven-roasted Brussels sprouts recipe?
The possibilities are endless as they are the perfect side dish to most food.
They are also the perfect party side dish.
Can the Brussels sprouts be made ahead of time?
They can be prepared to the point of being mixed with olive oil and then set aside. Once the Brussels sprouts are cut, they must be seasoned with oil, or they will turn to a dull brownish color.
However, since this dish is served warmly, I will not recommend preparing it early and warming it up at the last minute.
