Let’s talk about the definition of comfort.

For me, that word conjures up many things…sweatpants, chocolate, clean sheets and cheesy vegetable gratins that aren’t really all that bad for you to name a few.

We’ll get to that last one in a minute or two.

Now let’s talk about the definition of discomfort.

Prior to yesterday, I would’ve had many things on this list…allergies so bad you can’t see out of your tearing up eyes, 400m of burpees, breaking your big toe when the heaviest girl on the soccer team kicks it full force head on, stuff like that.

Now, however, I’m convinced that there is nothing that can define that word better than sitting through a 2 hour one on one sales pitch about time shares when you have absolutely no intent of buying one.

This little mini-vacation we’re on right now in Florida all started back in July when I was casually booking a Hilton hotel in Milan for a few nights for our Italy trip.

At the end of the call, they asked me to listen to their Hilton Grand Vacation packages that were available to me for being “such a loyal diamond member” and I said yes fully anticipating to listen to the quick sales pitch, say my usual “thanks, but no thanks” and hang up 500 Hilton points richer.

I’m a point whore and I’m cool with it.

But then I heard 4 nights for $150, 15,000 points and a $100 rebate and next thing you know, we’ve got a trip to Orlando booked.

Fast forward to Nov. 6 12:30pm at Mr. Porter Metcalf Jr’s desk at Hilton time share headquarters in Orlando, Florida and that “pretty good deal” is looking like it got run over by a train as I’m being assaulted to buy a timeshare.

I’m in sales.

I get the “sales pitch”, really I do.

But if someone were to tell me no, to my face, 7 (yes, 7) different times I’m pretty sure I’d say “well, thanks for your time” and move on.

Anyway, Porter was not me.


We sat there for 2 hours, politely declining “our chance to give our future kids (which we don’t plan on having) the vacations they deserve” over and over and o.v.e.r. again.

We were brought in front of sales managers, “diamond member” managers and then closing managers as if our “no, thanks” was a “YES, YES, YES! Pretty please, we want in” and it was the most uncomfortable 2 hours of my life.

I felt like I was released from jail after a 10 year prison sentence when we got in that elevator at the end.

We both just looked at each other and all I could say was “I’m sorry, I swear I’ll never even listen for the 500 points next time”.

But comfort…comfort is good.

And broccoli cauliflower gratins are hella good.

Especially when that cheesy, crusty topping isn’t a calorie bomb that defeats the purpose of the underlying vegetables in this one.

Do comfort.

Just don’t do time shares.

FAQs and Expert Tips

  • While you can store the leftovers and reheat later, gratins are best on the day you make it, so the topping is nice and crisp.
  • You can use this same recipe and swap out the veggies for something totally different. Brussels sprouts would be delish!
  • If you like, add in some ham, bacon or sliced sausage links for protein (or a one pan meal).
  • Make ahead dishes are great when you are feeding a crowd. To make this gratin beforehand, follow all of the instructions except for the topping. Whip that up just before you are ready to serve and bake it for the last 20 minutes.
  • For easy cleanup, grease your dish before you start.
  • Make sure your veggies are dry before placing them in the oven so they get nice and crispy.
  • Be sure to sprinkle almond meal on top and not almond flour. The meal is courser and gives more of the breadcrumb consistency. If you don’t have almond meal, you can coarsely pulse almonds in a food processor or blender to make your own.
  • Have leftover veggies? Try my buffalo turkey cauliflower skillet or buffalo broccoli cheddar bites.
What is a gratin?

Gratin is any dish that is baked with cheese, butter and/or breadcrumbs on top.

Can you make this broccoli gratin vegan?

Sure can! Simply swap the butter for a vegan butter. For the parmesan cheese, you can opt for a vegan cheese or nutritional yeast to get the same cheesy flavor.

Can I use frozen veggies?

For this gratin, I would not recommend frozen broccoli and cauliflower. We want them to crisp up and fresh produce works the best in this case.
