Slice a very thin layer from the very base of the fennel bulb so that the core still remains intact. Slice the stalks and any fronds and discard. Slice the fennel bulb into thin, half inch wide strips and thinly slice the shallot. Heat the oil in a skillet over a medium heat. Add the thinly sliced fennel and shallot and pan fry gently for 3-4 minutes or until fork tender.
Step 2
Add the butter to the skillet to melt then add the lemon juice, thyme, salt and pepper. Pan fry for 2-3 minutes more or until the fennel is softened and starting to caramelize around the edges. Serve hot.
