The best baked cauliflower cheese made with slices of fennel and baked in an absolutely delicious cheese sauce. It’s topped with, wait for it…more cheese and comes out of the oven bubbling, golden and smelling so delicious it’s hard to wait before getting stuck in!
Baked cauliflower cheese, the ultimate comfort food side dish.

Cauliflower cheese is a side dish I grew up with as part of a Sunday roast which consisted of either roast beef or roast chicken and a whole array of veggie side dishes. My Mum would pull out all the stops (and still does) but the thing we all loved the most was the cheesy, golden, baked cauliflower cheese.
It’s just pure comfort food and pretty much goes with any main course (almost) I mean, it’s even great on its own. If someone plonked a plate of baked cauliflower cheese down in front of me for dinner and nothing else well, I would not complain one bit.
I added a twist to this recipe by adding fennel and believe it or not baked cauliflower and fennel gratin is a delicious side dish from the North of Italy.
What Can I Add To Baked Cauliflower Cheese?
- Bacon
- Spring onions
- Leeks
- Broccoli (baked cauliflower and broccoli cheese, so good!)
- Different cheeses such as blue cheese (because why not?)
- You can also top it with breadcrumbs
How To Make Baked Cauliflower Cheese With Fennel – Step By Step
First, cut the green tops off the fennel (keep the fronds for garnish) cut it into thick slices and break the cauliflower into small florets. You’ll need to cut the stalk off the cauliflower first then it’s easy to break and cut apart (photo 1).
Boil the fennel and cauliflower in a large pot of salted boiling water for 3 minutes then drain and set aside.
To make the bechamel sauce, add the butter to a saucepan over a medium heat, once melted add the flour and stir to a thick paste. Let it cook for 1 minute whilst stirring (this cooks out the floury taste) (photo 2).
Next, add 1 cup (250ml) of milk whilst whisking to avoid any lumps (keep whisking until it thickens then add 1 more cup of milk. Whisk again until it thickens then add the final cup with a good pinch of salt, pepper and nutmeg. Once that starts to thicken add 1 cup (110g) of grated cheese and stir until it melts, turn off the heat (photos 3-6).

The Best Cheeses To Use To Make Cauliflower Cheese
For this recipe I used grated fontal cheese which is a common cheese found in Italy, it’s very similar to Fontina cheese which would be another good choice but it’s a little pricier. Here is a list of good cheeses you could use;
- Strong cheddar
- Smoked cheddar such as Applewood
- A mix of cheddar and blue cheese such as Gorgonzola
- Try topping the baked cauliflower with a mix of mozzarella and cheddar
- Fontina
- Fontal
- Gruyere
- Parmesan (use one of the above cheeses for topping)

Cauliflower cheese takes me back to childhood, but I’ve never had it with fennel. I do love the flavor of fennel, though, and can imagine it goes really well so might have to give this a try!
Definitely try it, it’s so good ๐
This cauliflower and fennel gratin looks scrumptious Emily, I love all the tips that you give about substitutions of veggies or cheese. I will try your wonderful recipe next Sunday, I’m sure the fam will love it!
Glad you found them helpful Patty, hope you enjoy it!
This looks and sounds fabulous. I have a cauliflower waiting to be made into this, just need to get some fennel. ๐
Thanks so much Stephanie!
That’s one cheesy masterpiece! Who needs mac n cheese when you have cauliflower! I bet fennel adds a really interesting flavor contrast. I’m always looking for new ways to use fennel. I plan to start growing it in my garden this year.
I love fennel this way, so yummy and that’s so great you’re planning on growing it!
I am addicted to white sauce. I can eat it out of a bowl with a spoon. To feel less guilty of course I add veggies. This looks like my comfort food. LOVE how cheesy and delish this looks.
Haha you and me both! Thanks so much Veena.
What a gorgeous dish. I bet my kids would love it too!
Thanks so much Sandi!
