Elevate your brunch experience with butternut squash rosti with fried eggs. This easy-to-make dish features a crispy butternut squash rosti, sauteed leeks, gruyere, perfectly fried eggs, and a dollop of zesty dill creme fraiche.
What makes this dish special
I love all types of squash. Butternut squash, kabocha squash, acorn squash, give me all of them. My husband, on the other hand, is not a fan. Well, I made it my mission to serve him squash that he would actually enjoy. Since he loves hashbrowns, I decided to make a butternut squash variation and whipped up these butternut squash rosti with fried eggs. Finished with a dollop of dill mustard creme fraiche and red chili flakes, I knew I would love them. As for my husband? Fortunately, he liked them too! Mission accomplished!
- Leek: A vegetable with a mild onion-like flavor, that adds flavor to the rosti. You can also use shallots instead.
- Butternut squash: A type of winter squash with sweet, orange flesh and a nutty flavor. You can also experiment with other winter squash such as kabocha squash, honey nut squash, or even sweet potatoes.
- Gruyere: A type of Swiss cheese with a distinct nutty and sweet flavor. Other substitutions include emmental, gouda, parmesan, or cheddar cheese.
- Creme fraiche: A thick and tangy cultured cream with a velvety texture. If you can't find creme fraiche, use sour cream instead.
- Dill: The aromatic herb adds a unique flavor to the creme fraiche. If you're not a fan of dill, use parsley instead or omit it for a mustard creme fraiche variation.
- Red chili flakes: Adds a bit of heat to the rosti, but can be omitted for a mild version.
How to make butternut squash rosti
Step 1: Make rosti mixture
So at this point, you may be wondering, what is a rosti? It's basically a hash brown where shredded potatoes (or in this case, butternut squash) are cooked in a pan. Rosti is usually one big cake but I turned them into individual cakes just to make it easier.
Let's start making the butternut squash rosti mixture. First, we're going to saute some leeks in butter until they are softened and tender. Leeks add another flavor element to the dish, adding a bit of savory to the sweet squash.
While the leeks are cooking, grate the butternut squash. I used a food processor with the grater attachment but you can grate the squash by hand. You'll need about 1 small butternut squash to get 4 cups worth.
Step 2: Pan-fry rosti
Mix the butternut squash with gruyere, leeks, egg, salt, and pepper. The rosti mixture is a fairly loose mixture but the egg does help bind it. Pan-fry the rosti, scooping ⅓ cup portions into the hot pan. I like to use a measuring cup to help shape the rosti into a cake, flattening the mixture in the pan to get it nice and crispy.
While the cakes are cooking, whip up the dill mustard creme fraiche and fry some eggs. I found that 1 egg was enough for 2 rosti cakes but you do you.
Top the butternut squash rosti with the fried eggs, dill mustard creme fraiche, red chili flakes, and extra dill. I was very pleased with this vegetarian meal not only because it was delicious in every way but because my husband ate his entire plate and thoroughly enjoyed it! Serve this as a main course or prepare just the rosti as a great side dish.
Frequently asked questions
Yes, you can prepare the butternut squash rosti mixture in advance and refrigerate it. Cook the rosti just before serving for the best texture.
Make sure the pan is well-greased with oil or butter before cooking each rosti. Using a non-stick pan can also help prevent sticking.
It's not recommended to freeze the uncooked rosti mixture as the texture may be affected. However, you can freeze cooked rosti and reheat it in the oven for a quick meal.
