Slow cooked = the sweetest way to enjoy fennel and onions! Serve alone as a side to chicken or seafood, or on crackers or thinly sliced toasted baguette for a crostini. You can also use it as a filling for a rustic tart.
- 2 large onions, halved then sliced lengthwise (root to tip) in 1/4-inch thick slices
- 2 large fennel bulbs, sliced into 1/4-inch thick slices
- 2 Tbsp butter
- 1/4 cup grated Parmesan
- 2 Tbsp chopped fresh parsley
- 1 teaspoon lemon zest
- 2 teaspoons lemon juice
1 Heat olive oil and butter in a large, uncovered, wide pan on medium high heat. Add the sliced fennel and onions and stir to coat. Stir occasionally. After about 10 minutes, sprinkle the onions and fennel with salt. Lower the temperature to medium. You want to strike a balance between allowing the pan to get hot enough so that some caramelization (when the natural sugars in the onion and fennel start to brown) and keeping the pot from getting so hot that the onions and fennel dry out. If it becomes an issue, you can add a couple tablespoons of water to the pan to help the onions and fennel to keep from drying out too much.
2 Stir occasionally, scraping up any browned bits from the bottom of the pan. Note that the browned bits are the tastiest parts. Cook for another 30 minutes to an hour, depending on how caramelized you want your mixture to be.
3 When ready to serve, remove from heat and toss in the freshly grated Parmesan cheese, the chopped parsley, lemon zest and lemon juice. Taste and add more lemon juice if necessary.
