Cauliflower Ham Casserole

Cauliflower replaces the potatoes in this comforting casserole, which I’ve been making for 30 years. Whenever we have leftover ham, my husband asks me to make this dish. —Sue Herlund, White Bear Lake, Minnesota

    This was one of the few ways to get my kids to eat cauliflower when they were younger. I was extremely surprised a few weeks ago when my son called begging for the recipe. I found out the girl he has been dating for six months has a very picky eater child. He wanted to see if this would win him over. We used French fried onions on it and he called me after saying the kid had seconds. He was really pleased and I am very happy that this is still a favorite

    I love this recipe! I first cooked the cauliflower to al dente. I topped it with Italian bread crumbs and only cooked it 25 minutes.

    This is an absolute favorite ... with a couple of minor changes to address the issues noted with the dish sometimes being watery. I replaced 1 cup of the milk and the mushrooms with a can of cream of mushroom soup for a creamy, cheesy side dish that has been a favorite at every covered dish event. Yummy!

    My husband doesn't like potatoes and I had, at my son's request, bought a head of purple cauliflower so when I saw this recipe, I decided to give it a shot. I didn’t have any sour cream so I used a little extra butter and milk instead. My husband and i both really wnjoyed this recipe and my daughter, who is usually leery of cauliflower, ate a healthy bowl for dinner as well. Telling her it was a bowl of purple and pink (ham) and adding a little feta and parmesan did help too.But I would definitely do this again! Not a good weeknight meal if you're in a hurry, as this recipe ended up taking closer to 1.5 hours than the one hour listed on the recipe. A winner in my book.

    I'm not a big cauliflower fan, but I thought I might enjoy it in this dish. I think it's a good recipe, but I probably won't make it again. I may try it using potatoes, since the cheese sauce was tasty and the recipe had a good balance of ingredients. I did use reduced fat sharp cheddar, light sour cream and fat free milk, and no one noticed. I also had to sub panko breadcrumbs, and we liked the topping. Since some people commented about it being watery, I returned the cauliflower back to the pot, after draining, to "dry" them for a minute or so, while stirring over medium-low heat.

    My family and I loved it! Will surely make it again. Being A cheese lover, I added a little Velveeta and used French fried onion rings on top in place of bread crumbs.

    This is a good recipe if you're trying to cut back on your carbs since most ham casserole recipes contain potatoes. I sauteed finely chopped onions and red pepper in the butter for extra flavor and left out the canned mushrooms. This does NOT reheat well since the leftovers become watery.

    Excellent recipe! The only change I made was to leave out the mushrooms. I noticed it was somewhat watery, but since no one else mentioned this problem, I must have either not drained the cauliflower enough or didn't let it rest before eating. I served this with a Greek salad and asiago cheese dinner rolls.

    This would be a lovely dish to serve for Easter. Have made it a couple times, and will continue, but seemingly forgot about it.
