Gluten Free Lasagna with Celery Root (Celeriac) Noodles

gluten free lasagna made with celery root on a plate

We all have foods we miss when we ditch wheat, and lasagna tops the list for a lot of us. Think about it – it’s the ultimate comfort food: gooey cheese, zingy sauce, meat if you like, sometimes your favorite vegetables, all layered between stacks of tender noodles. Well, pull out that lasagna pan because this recipe is going feel completely indulgent. This celery root lasagna is the real deal, without the brain fog and digestive discomfort you get from grains.

Even the most carb-addicted, pasta-loving person you know ask for seconds. In place of noodles, we’ll use thin sheets of celery root, a vegetable with a mild flavor and tender texture that does a fine job of impersonating a lasagna noodle.

Never had celery root before? Let’s get to know celery root, or celeriac, a little better.

What is celery root?

Celery root, or celeriac, is a bulbous root vegetable with a bumpy skin and flesh like a firm potato. Their neutral flavor makes them versatile – you can roast them, mash them, they hold up to stews and slow-cooking, and when sliced, they make a great replacement for lasagna noodles.

What does celery root taste like?

Celery root has a texture similar to a parsnip and a neutral flavor that resembles a potato with a subtle celery qualtiy. Its subtle flavor makes it play well in a wide variety of dishes, and it holds up well as a pasta replacement.

Is celery root keto? How many carbs are in celery root, or celeriac?

Celery root contains 3 net carbs per 1/2 cup, which makes it a great addition to a keto lifestyle. People use it as a replacement for noodles, potatoes, and other higher carb root vegetables because of it’s neutral flavor and versatility.

Do you have to peel celery root?

The skin is fibrous and earthy, so it’s best to peel celery root and cook with the tender flesh.

Time to give it a try in your new favorite lasagna recipe.

Directions

Preheat your oven to 350 degrees Fahrenheit. Toss your smashed garlic and sliced tomatoes in 2 tablespoons of olive oil and lay on a parchment covered sheet pan.

tomatoes for roastingRoast for about 45 minutes, or until they are soft and a bit caramelized.

While the tomatoes are roasting, fill a pot with water and a pinch of salt and bring to a boil. Wash your celery roots well and peel them. Slice them into very thin squares that are at least 1/8” thick but no thicker than ¼”. Reserve any odds and ends of the celery root for later.

Bring a pot of water with a pinch of salt to a boil. Drop your celery root sheets in (if your pot is smaller you may need to do this in two batches). Allow them to simmer in the water for a few minutes until you can just pierce them with a fork. Use a slotted spoon to remove the slices and allow them to drain on a piece of towel or paper towel.

Chop any remaining odd and end bits of celery root and place them in the water. Allow them to boil until they are soft. Remove the celery root pieces and set them aside in a separate bowl or plate.

In a blender, place the chopped up pieces of celery root and the butter. Blend together until smooth (you can use a little broth or water if the mixture is too thick) and then stir in a few tablespoons of the mozzarella. You should have about 1 cup of celery root puree in total.

Heat your remaining olive oil in a skillet over medium heat. Once hot, add the onion. Saute for 2-3 minutes, or until soft. Add the minced garlic and stir until fragrant, then add the ground beef. As the beef browns, add the salt, pepper and oregano.
