Marrow Shopping Tip: It’s hard to judge how much marrow you will get from any bone. Bone thickness is a decent indicator: a 3-inch bone will yield anywhere from 1–3 ounces per 30–90g of bone, but usually it averages around 1½ ounces per 40g.

The bones should already be free of meat and should smell clean and faintly meaty. The marrow itself should be whitish pink in color; don’t worry if you can see blood spots on the surface—that’s normal.

Step-by-step recipe

  1. Preheat the oven to 450°F. We'll start by making the roasted garlic, because it takes the longest to bake.

  2. Peel away the outer layers of the garlic bulb skin, leaving the skins of the individual cloves intact. Using a knife, cut off ¼ to a ½ inch of the top of cloves, exposing the individual cloves of video

  3. Drizzle a couple teaspoons of olive oil over each head, using your fingers to make sure the garlic head is well-coated. Cover with aluminum foil, as seen in the video in the previous step.

  4. Stick it in the oven! Bake at 450°F for 25-30 minutes, or until the cloves feel soft when pressed with a fork. While the garlic is baking let's make the vegetable casserole!

  5. Clean and chop up all your veggies for the casserole.

  6. Add your veggies to the casserole dish in layers. Two layers should be plenty, but feel free to stack to the sky. Pause between each layer to add ½ tbsp olive oil, salt and pepper and ¼ cup of cheese. (I also added a small amount of cream to make the casserole a bit creamier.)

  7. Top off your casserole with a layer of cheese and slip it into the oven to cook for 30 minutes, or until the casserole is golden on top and bubbling.

  8. Now for the highlight ingredient, luckily it is the easiest part of the meal to make! Take the bones out of their packaging, wash them off and pat them dry.

  9. Place the marrow bones in a roasting pan. Season them with liberally with salt and pepper.

  10. Roast for 20–25 minutes at 450°F, or until the bones and marrow are golden brown.

  11. Serve and eat immediately with a spoon. It pairs wonderfully with the roasted garlic!

    You'll notice we also grilled up a flank steak. Get a nice cut at Whole Foods, season it, and toss it on the grill for a great companion to the marrow and vegetables!
