Boneless Roasted Leg of Lamb with Potatoes and Fennel

This is the first year in as long as I can remember that we won’t be celebrating Easter or Passover with family. It’s one of those unusual years when both holidays land in the same week and my kids have spring break. So we’ve decided to ditch Jersey and head to New Orleans to introduce the kids to the Big Easy. Beignets, gumbo, muffuletta, po’ boys, red beans and rice, pralines…the deliciousness goes on and on. Yes, of course I know that there’s much more to Nola than food, but I’m hungry as I’m typing this and it’s all I can think of right now. And, I mean, the food is seriously amazing.

But as much as I’m looking forward to our trip, especially since March has been pretty miserable weather-wise in the northeast, I am sad about missing out on the holidays. Both Easter with my family and Passover with my husband’s are steeped in tradition, and of course much of that tradition centers around food.

Growing up, we had a special version of these classic Italian cookies baked with hardboiled eggs and drizzled with icing for breakfast. We spent the morning searching for our Easter baskets and once found, sneaking as much candy as we could. I looked forward to wearing a pretty new dress for church and once or twice even sported an Easter bonnet. Yes, an Easter bonnet. I remember my favorite was covered in white and yellow daises and tied in a bow under my chin. (Ah, to be young in the late 70’s.) Easter dinner was served midday and of course followed up with more bites of chocolate bunnies and trying to pawn off those licorice flavored jelly beans to my brothers.

As an adult, I always look forward to celebrating Passover with my husband’s family. The Seder table is beautifully set, the mood festive and the food delicious.  We look forward to sharing the traditions that are unique to his family each year…the special songs, inside jokes, sentimental toasts and of course, the killer matzo ball soup. I typically bring dessert, which always includes coconut macaroons and usually something chocolatey. And I’m particularly partial to toffee matzo brittle, aka crack 😉  Check back next Tuesday because I’ll be sharing that recipe and I promise you don’t want to miss it.

And speaking of recipes, let’s get to today’s shall we? Roasted lamb is equally appropriate for Easter dinner or the Passover Seder. To keep it simple, I opted for a boneless leg of lamb that my butcher had all nicely trimmed and tied for me. I made an herb gremolata (an herb/garlic/lemon zest condiment) and blended it with olive oil and slathered it all over the lamb before roasting. I added baby potatoes and sliced fennel to the roasting pan for an easy side and love the way they absorb all that flavor from the lamb and the rub.

This is one of those dishes that is as easy as it is elegant, especially if you purchase it already trimmed and tied. I start it off on a high heat to get a nice crust, then reduce it for the remainder of the cooking time. My family prefers lamb medium rare – medium so I cook it to an internal temperature of 130 degrees and then let it rest for 15 mins before slicing (the internal temperature will rise an additional 5-10 degrees while it rests). The result is light pink roast, with a caramelized crust and wonderfully tender slices. As bummed as we are to not share the holiday with family this year, at least we got to enjoy this lamb roast as conciliation. Though no doubt it would have tasted even better shared with family.

Course: Main Dish
Author: Cathy |
  • 3 lb boneless leg of lamb trimmed and tied
  • 5 medium cloves garlic chopped
  • 2 Tbsp fresh parsley chopped
  • 1 Tbsp fresh rosemary chopped
  • 1 Tbsp fresh mint chopped
  • 1 tsp dried oregano
  • 1 Tbsp lemon zest about 1 lemon
  • 2 tsp kosher salt
  • 1/2 tsp freshly ground black pepper
  • 1/4 cup extra virgin olive oil
  • 2 lbs baby potatoes halved or quartered so they are uniform in size
  • 1 medium fennel bulb fronds trimmed, cored, halved and then thinly sliced
  • salt and pepper
  1. Remove the lamb from the refrigerator and allow it to come to room temperature (at least 1 hour).
  2. Preheat the oven to 450 degrees.
  3. In a small food processor combine the garlic, herbs, zest, salt, pepper and olive oil and process until smooth. Place the lamb in a shallow roasting pan and cover completely with the herb mixture. Rub the mixture all over the lamb.
  4. Roast, uncovered, for 15 mins.
  5. While the lamb is roasting, cut the potatoes and the fennel. After the lamb has roasted for 15 mins at 450 degrees, reduce the oven temperature to 400 degrees and scatter the potatoes and fennel around the lamb, tossing well with the herb mixture on the bottom of the pan. Sprinkle with salt and pepper.
  6. Return the pan to the oven and cook until an internal temperature of 130 degrees is reached (medium rare), about 45 mins.
  7. Remove the pan from the oven and place the lamb on a ridged cutting board and cover with foil. Allow the lamb to roast for at least 15 mins before slicing. Give the potatoes and fennel a good toss and return to the oven for a few mins if needed until they reach your desired degree of doneness (I like golden brown veg).
  8. Remove the butchers twine, slice the lamb and serve on a platter with the roasted vegetables.

    Hi Cathy
    Your blog is just a feast for the eyes and enrichment for the soul at the same time. (Its also a dream to navigate.).
    Of course, I particularly loved reading your recollections about Passover! So special….beyond words. You will all be sorely missed this year. Travel safely

    • Cathy says:

      Thanks so much Lauren. Means so much to hear. We missed sharing the holiday with you all and we need to get together soon. xoxo

    Can’t wait to try this recipe
    Looks amazing

    Oh, this looks so delicious. I have never cooked a leg of lamb before, it’s always freaked me out a little (not a whole lot of lamb down here in the South) but I love to eat lamb! I need a good Easter dinner recipe so this may be it!
    BTW, have lots of fun in NOLA! It’s such a beautiful city and the food is ah-mazing. My favorite thing to eat there is Eggs Sardou which I believe you can find at Antoine’s (and a few other places I’m sure).

    • Cathy says:

      Thanks Jodie! We had the best time in NOLA and ate our way through the city, but believe it or not never had the eggs sardou at Antoines! Next time!

    This looks gorgeous. I LOVE lamb and i love it when it’s nice and simple gremolata mmmm

    • Cathy says:

      Thanks Maria. I agree, a simple gremolata or marinade is all you need with a nice cut of lamb.

  5. You are so talented. This looks perfectly cooked and to capture ‘perfectly cooked’ in a photograph is elusive at least in my opinion. Great job love stopping by!

  6. This looks absolutely stunning Cathy. Being Persian, my hubby is a huge lamb fanatic so saying that he would be thrilled to see this show up on the table is a huge understatement. As for us. . .well, we’ll be spending Easter in Boston as the hubby will have just returned from Japan. Perhaps I should be the superstar wife and surprise him with this beauty.

    P.S. Have fun in Nola.

    • Cathy says:

      Thanks so much Lynn. Lamb was a favorite of my family growing up. We would grill it all the time during the summer. Hope you had a great Easter!

  7. Cindy says:

    Awww, sounds like the trip will be awesome, but you will be missing the family and those awesome traditions you named. I am sure they will be missing your treats too this year, but it will make next year that much sweeter for you and yours. Nola will be amazing. Enjoy – You deserve it.

    I made this last night. Delicious! I had to omit the mint since I couldn’t find any, but other than that I made the recipe as written. I removed the lamb at 130 degrees and let it rest 15 minutes while the veggies finished cooking. It was perfectly cooked to medium rare when we sliced it. The flavors were wonderful. This is a keeper.

    • Cathy says:

      So nice to hear from you Debbie and happy you enjoyed the lamb. This is a spring favorite for the holidays in my house and never disappoints. Thanks for taking the time to share!
