Pumpkin Risotto Frittata with Mushrooms

The natural sweetness of pumpkin plays well with the savory, earthy notes of fresh mushrooms in this rustic risotto frittata. A cast-iron skillet does double duty for cooking and keeping this hearty dish warm for serving. Fresh gremolata on the side adds color and bright flavor.

By Shelli McConnell,


  • 1 lb. assorted fresh mushrooms (such as shiitake, cremini, and button), sliced
  • 1 tablespoon tamari
  • Freshly ground black pepper, to taste
  • 1 32-oz. container low-sodium vegetable broth
  • 2 medium leeks, halved and sliced (2 cups)
  • 6 cloves garlic, minced
  • 2 cups dry short grain brown rice
  • 1 15-oz. can pumpkin
  • 2 tablespoons flaxseed meal
  • ½ cup dry whole wheat breadcrumbs
  • 2 tablespoons lemon juice
  • Sea salt, to taste
  • 2 tablespoons finely chopped fresh Italian parsley
  • 1 tablespoon finely chopped fresh basil
  • 1 teaspoon lemon zest


  • Preheat oven to 450°F. Line a large shallow baking pan with parchment paper. Spread mushrooms in a single layer in baking pan. Sprinkle tamari and pepper over mushrooms. Roast about 25 minutes or until golden.
  • Meanwhile, for risotto, in a medium saucepan bring broth and 2 cups water to simmering over medium. In a large saucepan cook leeks and 4 of the garlic cloves over medium about 5 minutes or until tender, stirring occasionally and adding water, 1 to 2 Tbsp. at a time, as needed to prevent sticking. Add rice; cook and stir 1 minute. Add ½ cup hot broth to rice; cook, stirring constantly, until liquid is almost absorbed. Continue adding broth ½ cup at a time, making sure most of the liquid is absorbed before adding more, until all liquid is absorbed and rice is just tender, about 45 minutes. Stir in pumpkin.
  • Meanwhile, in a small bowl stir together flaxseed meal and ⅓ cup water; let stand 10 minutes. Stir flaxseed mixture, bread crumbs, roasted mushrooms, and lemon juice into risotto. Season with salt and pepper.
  • Reduce oven temperature to 350°F. Spoon risotto mixture into a 10-inch cast-iron or oven-going skillet, spreading into an even layer. Bake 40 minutes or until top is dry and frittata seems set. To transport, cover skillet and wrap in a towel.
  • For topping, stir together parsley, basil, lemon zest, and the remaining 2 garlic cloves. Place in a resealable plastic bag to transport.
  • To serve, uncover skillet. Cut into wedges and sprinkle with topping.

Step #2 makes no sense. You have both medium and large saucepans, adding 2 cups of water and yet adding tbs into the leek to prevent sticking. And then you add rice and what do you do with the medium saucepan with the 2 cups there? Or...


The water/broth mixture in the medium saucepan gets added, 1/2 cup at a time, to the risotto in the large saucepan (see second half of step 2). The purpose of the medium saucepan is to keep the water/broth mixture hot until you’ve added all of it to the large saucepan, otherwise it would cool the rice and interrupt its cooking every time you add some to the large saucepan. Hope this helps !


What do we do with the other 2 garlic cloves? How about the basil and the parsley?

Hi Anna, those are for the gremolata; we'd accidentally left a step out of the instructions, but the recipe has now been updated. Sorry for the oversight!


Can you freeze this?


Parsley, basil and lemon zest are for the top after baking?


And what to do with the two extra minced garlic cloves?


Just looked up a gremolata recipe and got my answer--chop all together and serve on the side.jody

Hi Jody, We're sorry for the oversight! We've updated the recipe to include a step with instructions for making the gremolata. Thanks for bringing this to our attention. Warm regards, Courtney Davison Managing Editor Forks Over Knives


Can the leftovers be frozen? I added a bit of spice and it was delicious!

Comfort food that’s perfect for a chilly, damp day. I don’t have a cast-iron or an oven-going skillet, so I baked it in a casserole dish without any problem.
