  • 1/2 cup water
  • 1 large (or 2 small) yellow onion(s) about 15 ounces in weight, sliced thin
  • 2 garlic cloves
  • pinch dried thyme
  • pinch red pepper flakes
  • 1 bay leaf
  • 1/4 tsp sea salt
  • 1 Tbsp olive oil


  • 1 pound Brussels sprouts ends trimmed
  • 1 cup cheddar cheese grated
  • 1/2 cup breadcrumbs (see Notes for how I make my own breadcrumbs)
  • 2 Tbsp olive oil
  • sea salt to taste


  • Begin by heating the water for the 'cream' sauce in a 8-9 inch pan.
  • Add in the onion, garlic, thyme, pepper, and bay leaf.
  • Bring the mix to a simmer, then reduce the heat to medium low.
  • Cover the pan with a fitted lid, and let the onions cook for 20 minutes, stirring once or twice in the interim.
  • While the sauce is cooking, halve your Brussels sprouts and steam them in an appropriate pan for 10-11 minutes, until fork tender. Alternatively, you could boil them, but I feel they lose more nutrients that way.
  • Once the sprouts are steamed, deposit them onto a cutting board, and (when cool enough) chop them into bite-size pieces.
  • Oil or butter an 8 x 8 inch baking dish, and spread the sprouts across the bottom.
  • Preheat the oven to 400 degrees, at this time.
  • Once the onion mixture has cooked for 20 minutes, remove the bay leaf, and add it to a high speed blender along with the olive oil.
  • Blend until smooth, adding salt to taste. Add in a splash of water if needed for blending.
  • Pour the 'cream' sauce atop the Brussels sprouts, giving it a little mix with a spoon.
  • Top the mix with the cheese, mixing it in a bit as well, if you like.
  • Mix the breadcrumbs with the two tablespoons of olive oil and a dash of salt.
  • Spread the breadcrumbs atop the cheese.
  • Bake for 20 minutes until bubbly.
