Italian sausage and fennel frittata
Fennel has never been a regular ingredient in my kitchen, mostly because its licorice aroma can seem stronger than its flavor. But once it softens in the skillet, it turns mellow and slightly sweet. Paired with Italian sausage, eggs, and Pecorino Romano, it becomes one of those simple dinners that feels a little more special than the effort it takes

I had a fennel bulb or two in the fridge, and I waited all week to make Italian sausage and fennel frittata with a side of fresh-baked Italian bread and an arugula salad with a Dijon vinaigrette. While the frittata was under the broiler, my grandkids stopped by unexpectedly. I almost offered to make something else because the kitchen smelled so strongly of fennel. Instead, Simone happily claimed most of the slice on my plate. She loved the sausage and fennel together. Dominic, meanwhile, was far more interested in M&M’s than vegetables.

Ingredient notes
Fennel’s licorice bite mellows once it hits the skillet, and you can save the fronds for garnish; sweet Italian sausage keeps the dish balanced, though hot Italian sausage works if you want the extra kick; Parmesan stands in fine for Pecorino if that’s what’s in the fridge.
Recipe Tips
Slice the fennel into small, even pieces so it softens at the same rate as the onion. When cooking the frittata, I use a well-seasoned cast iron skillet for easy release. Be careful not to overcook the fennel. I should soften without browning too much. Cook the eggs until a slightly wet top forms. Keep a close eye on the broiler, since the frittata can go from golden to overbrowned quickly.

Italian sausage and fennel frittata
Ingredients
- 1 fennel bulb cleaned and chopped
- ½ cup red onion chopped
- ½ lb sweet Italian sausage casing removed
- ¼ cup extra virgin olive oil
- 10 eggs
- 2 tbsp grated Pecorino Romano cheese
- ¼ cup heavy cream
- salt & pepper
Instructions
- Preheat the broiler, with the top rack about 6 inches from the top.
- Heat olive oil in a 10-inch cast-iron skillet over medium heat. Cook Italian sausage until almost done. Then, add onions and fennel and cook until soft, about 5-7 minutes, stirring occasionally to prevent sticking.
- Whisk the Romano and cream with the eggs. Pour the eggs over the sausage and fennel. Gently stir once or twice to distribute the filling, then stop stirring and allow the eggs to cook undisturbed until nearly set.
- Put the skillet under the broiler until the top of the frittata is set and browned, about 3-4 minutes. The frittata should be firm to the touch and slightly puffed when done.
Notes
- Use a well-seasoned 10-inch cast iron skillet.
- Watch the broiler closely during the last few minutes.
- Let the frittata rest for 5 minutes before slicing.
Variations
- Add spinach
- Substitute turkey sausage
- Add roasted red peppers
- Sprinkle mozzarella over the top
- Use goat cheese instead of Romano
Storage
Refrigerate leftovers for up to 4 days.
Reheat gently in the microwave or in a skillet over low heat.
Frequently asked questions
Can I make frittata without a cast iron skillet?
Yes. Any oven-safe, 10-inch skillet works well. If your skillet can’t go under the broiler, cook the eggs on the stovetop until almost set, then transfer everything to a lightly greased baking dish and finish it in a 375°F oven until the center is set.
Can fennel be eaten raw?
Absolutely. Raw fennel has a crisp texture and a pronounced anise or licorice flavor. Thinly sliced fennel is delicious in salads and slaws. When cooked, however, the flavor becomes much milder and slightly sweet, making it an easy introduction for people who aren’t sure they like fennel.
Can I freeze frittata?
Yes. Let the frittata cool completely, then slice it into individual portions. Wrap each slice tightly and freeze for up to 2 months. Thaw overnight in the refrigerator, then reheat gently in the microwave or in a 325°F oven until warmed through. The texture will be slightly softer after freezing but still very good.
What goes well with sausage and fennel frittata?
This frittata pairs well with simple sides that balance its rich flavor. I like serving it with fresh-baked Italian bread, an arugula salad with Dijon vinaigrette, or fresh fruit for breakfast or brunch. Roasted potatoes or a bowl of seasonal fruit also makes it a satisfying light dinner.
Can I make this ahead?
Yes. You can cook the frittata a day in advance and refrigerate it, covered, until you’re ready to serve. It tastes just as good reheated gently in the oven or microwave, and it’s also delicious served at room temperature, making it a great choice for brunches, holiday breakfasts, or meal prep.
