Nutritious Eggs Made Into A Frittata Is Good Any Time Of Day

Ever since Mrs.CBB started making changes to her diet to incorporate the keto methodology we’ve been working on new keto recipes.

Fennel Fronds are delicious so don’t throw them away

This keto baked frittata with mozzarella and fennel greens also known as fennel fronds is flavourful and cheesy gooey.

Fronds are those cute frilly green leafy things attached to the stalks that grow out of a fennel bulb.

They kind of look like fresh dill, and they have a texture that’s light and feathery.

The flavor of fennel fronds is very similar to the bulb that they come with.

Fennel tastes a bit like licorice, equal parts bright and vegetal, and when you roast or caramelize fennel, it develops a natural sweetness that balances out its bitterness.

Ways To Use Fennel

If you have never tried fennel before you must dive in and spend a few dollars to buy one.

Fennel is crunchy like celery but has an anise flavour to it that is gorgeous to eat raw, in salads or you can roast, grill, and saute it.

For this baked frittata recipe I only used the fennel greens as opposed to just the fennel bulb since most people don’t know what to use the fronds for and toss them in the garbage.

You can use the fennel fronds to infuse water to make a healthy tea, fennel infused oil, stuffed in fish, or to make a lovely soup stock.

The sky really is the limit if you love the flavour of fennel fronds when cooking and adding it to your favourite recipes.

How To Clean Fennel

When I use the fennel bulb I chop the tough stems like cabbage after I slice the fennel in half and remove the stalk and fronds.

I rinse each layer of the fennel one by one tearing it apart. Once dry you can slice it, chop it, Julienne, or even shave it which looks simply amazing on any dish.

Most often I chop up the fronds and stalk then add them to a recipe as I would a fresh herb such as parsley, basil, etc.

If I have any fennel fronds leftover I will put them in a freezer bag and use them for stock or I add them to recipes as I need them.

You can even store the greens in the refrigerator for up to a week and use them as needed.

Another favourite way to use the greens is to blitz them in the food processor with butter, wrap in plastic, refrigerate then slice as needed to have a lovely fennel fronds butter.

Eliminate Food Waste

I’ve learned not to waste anything in the kitchen if I can because food waste in Canada is a huge problem that needs to be recognized by more people.

Lastly, I like to use the greens as a garnish or just sprinkled on top of a meal like I have with this baked frittata recipe today.

How To Make The Perfect Baked Frittata

The key to making a successfully baked frittata in my opinion is to cook it low and slow.

I start the frittata on the stove-top then finish it in the oven.

You will notice your baked frittata rise like a cake would but it will deflate after you pull it from the oven and it cools.

When I pre-heat the oven I’ll have it set at 250 degrees and let the baked frittata cook for about 10-15 minutes until golden and then add fresh mozzarella and fennel greens on top for flavour.

If you’re hosting a brunch this is a gorgeous presentation, especially during the summer.

There is something about the fennel garnish that makes this dish seem richer than you think.

What I like is a thick slice of frittata that can be used as part of a meal or inside of a sandwich.

My wife and I make a baked frittata and put it inside between low-carb, keto oopsie rolls for breakfast which are delicious and easy to make.

How To Make Baked Frittata (Mozzarella and Fennel Greens)

If you have a cast-iron pan now is the time to use it otherwise you can make this oven frittata on the stove-top exclusively using a frying pan cover.

However,  like us, we have an oven-safe frying pan or a deep dish pie dish so we can still make a baked frittata in the oven.

Side-Dishes To Eat With A Baked Frittata

What to serve with frittata?

You can add a side of pork and beans, a garden salad, tangy Cole-slaw, raw vegetable slices, bacon, sausages, ham, or soup.

You can even serve on top of last week’s blog recipe from Nicola, potato waffles.

Whatever you’d like to have a side would likely work as this is such a basic and versatile frittata recipe.

  2. In a mixing bowl crack eggs, add whipping cream, salt, and pepper then mix vigorously for about a minute. You can also use a stand or hand mixer if needed.
  3. Heat your stove-top to about 5 on the dial and sit your frying pan on top of the element to heat up with 2 tablespoons of butter
  4. Once melted added the egg mixture to the pan
  5. With a side to side, motion swirl the eggs around the pan until they start to settle
  6. Use a fork and gently lift the corner around the frittata to let the egg mixture go underneath the frittata so there isn’t so much on the top
  7. Put in the oven to bake for 10 minutes. Around the 5 minute mark add your mozzarella cheese and fennel greens
  8. Remove from oven with an oven mitt and let sit for 2-5 minutes before cutting into triangles

  1. Looks yummy!! Not big on fennel but as this is such a basic recipe,(the best kind to fudge with!!) I can see lots of possibilites here. I would double it here for the 4 of us but I gave a big cast iron fry pan as well as a slightly smaller one to use. I think my Paderno non stick can handle that temperature in the oven as well. I see a sneaky way to clear up veggie leftovers!!!
