I’m so in love with this time of year, the bright blue skies, flowers popping up everywhere, the longer days, spring break with my kids all home, and Easter – all right around the corner.

I’m reminded of why I should love, and be so grateful for, this day – with all of the beauty around us.

But first, this cauliflower gratin recipe! If you love Potatoes Au Gratin, or Potato Gratin Muffin Stacks, then you’ll love this low-carb dish. It’s super easy; undercook the cauliflower (boil), and add in the bacon and homemade cheesy sauce.

Bake with bread crumbs and chives!

Bob Goff, Love Does (book)

Bob Goff is not only a joyful, playful person, he gets the meaning of living. In fact, I wrote about it before, (I want my life to be fueled by love).

The call on our lives to truly be present and live in the moment …

“There is only one invitation it would kill me to refuse, yet I’m tempted to turn it down all the time. I get the invitation every morning when I wake up to actually live a life of complete engagement, a life of whimsy, a life where love does.

It doesn’t come in an envelope. It’s ushered in by a sunrise, the sound of a bird, or the smell of coffee drifting lazily from the kitchen.

It’s the invitation to actually live, to fully participate in this amazing life for one more day. Nobody turns down an invitation to the White House, but I’ve seen plenty of people turn down an invitation to fully live.”

– Bob Goff, Love Does

Make a simple invite

One simple way that I can reach out to people is to invite them over for dinner.

Loving Ranunculus flowers

Since it’s a gorgeous season for ranunculus flowers, I was thrilled when I saw these staring at me in Fred Meyer.

I loaded my cart and brought 3 home, and have been enjoying them since.

Two are now planted in an outdoor pot, and it sure is fun to buy grocery store flowers, enjoy them for a tablescape, and then eventially put them where they really are happy – in a garden pot.

  1. Love Bob Goff.  

  2. Can you use frozen cauliflower?

  3. Could you use arrowroot powder in place of the flour? I am on keto so I cannot have the flour or breadcrumbs.
    Thank you!

  4. I’m very happy with the way the cheese sauce came together, and I added 2 cups of broccoli for greenery and color to the 6 cups of cauliflower. So good! Thank you for a great vegetable recipe.

  5. This looks delicious, however, it’s not low carb.

  6. Just when I was looking for a veggie-based dish for the weekend, yay!
    I think this would taste good with broccoli, too.

  7. Thank you so much!!!!!! Will be divine!!

    Thanks also for the inspirational words!!xoxoxo

  8. I would love to take this to a thanksgiving pot luck. It’s an hour an 10 min away. Could I make it and put in a crockpot on warm? Would it be mushy? 

  9. I am making this for an Easter side dish. I was curious if I can make this Saturday, leave it in the fridge overnight and bake on Sunday? Would that make the cauliflower too mushy or not turn out the same? 

    • Sorry, I didn’t get back with you on this. Did you try to make it up ahead of time? I think it would be fine, as long as you bake it fresh!

  10. Does this dish re-heat well? I wanted to make it a day ahead of time.  Mostly concerned that the cauliflower could end up mushy.   If no worries, any suggestions on time and temperature to re-heat it? 

  11. I’m going to try this but as my hubby is following a ketosis diet I’ll substitute Almond milk in place of the regular and use crushed pork rinds in place of the bread crumbs.

  12. I made this last night and it was really, really good. I used it as a main dish with a green salad as a side (lemon vinaigrette–acidity to cut the richness of the main dish). I will say that I originally tried the proportions you listed to make the bechamel sauce, even though I thought they might be a bit off, and indeed, the flour/ butter turned into a dough. So, I threw that out and started over using the bechamel proportions I’ve used in the past–5 tbs butter, 4 tbs flour, 4 c half and half, and about 2 tsp salt and 1/2 tsp freshly grated nutmeg. (For others reading this who have never made bechamel: melt the butter over medium-low heat, add flour while whisking, and allow it to become a sandy/ golden brown. You may need to turn the heat to medium for this. Then, add in the half and half a cup at a time and turn the heat up to almost boiling while you whisk it. It should take about 7-10 minutes for it to get thick.) Anyways, it could’ve just been me who had that experience with the dough forming, but I wanted to offer the suggestion, should others encounter it. Hope you don’t mind! I also garnished with chives, like you had in the pictures. The end result was quite delicious. I gave some to my mother, who says she hates cauliflower, and she even loved it. Thanks for the great recipe! :)

    • Thanks for your input Meredith. I had several friends make it for Easter this year who told me they loved the recipe! :)

    • Great, Sandy! Then the issue was likely just a fluke! :) I just defrosted some leftovers for dinner. Yummy!

  13. I am absolutely, positively going to make this. We love every ingredient listed. :)
