If you don’t think that you like Brussels sprouts, it’s probably because you had them boiled or from a freezer bag. Give this recipe a try, it’s won over many!

So, you probably just haven’t had them when they were cooked to be their best selves. They go extremely well with bacon, pancetta, and/or cheese because they love salt. You can even balance the bitterness with something sweet like brown sugar or balsamic vinegar.

The best way to cook Brussels Sprouts is to roast or sauté them (in a skillet or you can roast them on a sheet pan in the oven. It softens them but also creates a crispy edge for added texture.

When you buy your sprouts, make sure they are firm, tightly layered, and the leaves aren’t shriveled nor have holes. Look for a nice green color, but it’s fine to have an occasional outside yellow leaf that you can pull off.

Most are sold individually by the pound or in a bunch. If you find them still on the stalk, get them! They are fresher and will stay that way longer. Put them in a vase, just like you would do with flowers, and remove them from the stalk when you’re ready to use them.

 How to prep your Brussels sprouts?

  1.       Hold them sideways on your cutting board and cut the bottom stem off
  2.       Remove any damaged or yellow leaves and discard
  3.       Then cut the sprouts lengthwise in half through the stem

To cook, use a cast iron or stainless steel skillet so that you can transfer it to the oven when you’re ready to brown your breadcrumb topping.

Now, as I said, sautéed sprouts are wonderful, so you could stop after you sauté them.

But why?!?

I thought I’d share this with you…
