For the Brussels Sprouts:

  • 1.5 lbs brussel sprouts
  • 2 tbsp extra virgin olive oil
  • 1/2 tsp freshly cracked black pepper
  • 1 tsp kosher salt

For the Sauce:

  • 2 tbsp salted butter
  • 1.5 tbsp gluten-free flour I use Bob's Red Mill 1 to 1 baking flour. You can sub regular, all-purpose flour here.
  • 1/4 cup dry white wine
  • 1/2 cup heavy cream

FAQs

Why do you soak brussel sprouts before cooking? ›

Although a healthy vegetable, consuming too many Brussels sprouts can be unsuitable for people on anticoagulants since it contains vitamin K, which results in blood clotting. Another issue with consuming Brussels sprouts excessively is that it can lead to gas and bloating.

Why do brussel sprouts taste bad sometimes? ›

These bitter tasting compounds are an important part of the plant's defence mechanism against leaf-eating enemies, such as insects, nematodes, slugs, and herbivores, like pigeons and deer.

Are Brussel sprouts better roasted or sauteed? ›

If they're cut in half, roast them with the cut side down to make the most out of their sweet roasted flavor. Sauteing, another dry heat method, is great for Brussels sprouts too. If you do opt for steaming, just be sure not to overcook the veggies—five to seven minutes should do it.

How do you keep Brussels sprouts from drying out in the oven? ›

What is one major side effect of eating Brussels sprouts? ›

However, the natural agents that protect them from early germination can wreak havoc in our digestive system. Soaking and sprouting replicates germination, which activates and multiplies nutrients (particularly Vitamins A, B, and C), neutralizes enzyme inhibitors, and promotes the growth of vital digestive enzymes.

How do you get the bitterness out of brussel sprouts? ›

A splash of lemon juice, or even apple cider vinegar, works wonders on bitter sprouts. Another key ingredient is fat, which helps Brussels sprouts to crisp up. This is why it's so popular to render bacon fat and cook Brussels sprouts in it, then add the bacon bits back in at the end.
