Cauliflower, ham and rainbow chard baked in a cream sauce loaded with gruyere and topped with crispy bread crumbs. This is comfort food at it’s best!Ham and Cauliflower Gratin with Rainbow Chard

Well, well, what do we have here? That’s right – a meal centered around vegetables! I feel like its been a while, but its just so hard for me to get inspired by veggies this time of year. This dish makes the best of what’s in season with cauliflower and chard. Yes, cauliflower. I know what you’re thinking, but trust me – that cauliflower is getting mixed with cheese and cream sauce. Because cheese and cream sauce can make just about anything taste good.

Cauliflower gratin with rainbow chard, gruyere, and ham. If you have leftover ham from the holidays, this is a delicious way to use it up!I’ll admit, I was a little nervous about how this was going to come out: I figured it would either be totally gross or totally awesome. It was way better than I ever imagined it could be! We both loved it, and I happily gobbled it down while already looking forward to the leftovers. The cauliflower was tender without being mushy, and the chard was slightly bitter in a way that cut through the creamy sauce very nicely (it reminds me of the Brussels sprouts in this dish). If you must, think of this as a grown-up version of macaroni and cheese with cauliflower standing in for the pasta. You wont be disappointed. This is definitely a dish that I’ll be making again and again all winter.

At first I was planning for this to be a vegetarian dish, but I felt like it needed something to round the flavors out. I added just a tiny bit of cubed ham, and it was PERFECT. It added a touch of smokiness and saltiness and brightened the flavors just enough. Of course if you’d like this to be a vegetarian dish you can leave them ham out. In that case, I would add a few dashes of hot sauce to brighten the flavors.

  • 1 small head cauliflower about 1.5 lbs
  • 2 Tablespoons butter
  • 1 tsp Dijon mustard
  • 1 cup nonfat milk
  • 1 cup chicken stock
  • 2 Tbs flour
  • ¼ tsp nutmeg
  • 1 bunch rainbow chard chopped
  • 2 cups cooked ham diced

  • 1 ounce shredded Parmesan cheese
  • 2 Tablespoons breadcrumbs


  • Preheat oven to 350ºF. Bring a large pot of water to a boil.

  • While the cauliflower cooks, melt butter in a small saucepan over medium-high heat. Add the flour. Cook, stirring constantly, for 3 minutes or until light golden brown. Whisk in the milk, stock and mustard. Bring to a simmer and cook until the sauce thickens, about 5 minutes. Stir in the nutmeg. Slowly stir in half the gruyere.

  1. I really liked this recipe.
    I think I’d prefer it without the ham as a side dish and with it as a more complete casserole.

  2. I was searching for a seasonal recipe tonight and came across this one! I love chard and it’s not that common here in Amsterdam but found baby chard and made it with bacon instead of ham. All turned out really great! Thanks for the recipe!
