Mushroom Toast, Avocado-Corn Soup, and Basil Shoestring Fries

Mushroom Toast, Avocado Corn soup, Basil Shoestring Fries | bettysliu.comWhen I was in college with a limited ground-floor kitchen and close to zero cooking abilities, I used to go to local cafes and get my favorite combination: grilled cheese with tomato soup, with a side of fries. Delicious, but not exactly the healthiest choice of meals. So, when Salt for Life reached out to me to create three better-for-you recipes with their low sodium salt, I immediately thought of that classic comfort meal, only a little more self-conscious. Mushroom toast was my first thought, and one that would become the starting point of this meal. I eat mushroom toast at least once a week. Lightly toasted sourdough bread topped with gently sautéed mushrooms and scallions – you’ve seen me drool over this on instagram before, and I’m so happy to finally share my go-to on the blog!!! A slightly spicy avocado corn soup, served either warm or cold, complements this toast. It’s naturally creamy, without the addition of any creams, and can be topped with a dash of olive oil or sautéed corn kernels. The last accompanying dish is the indulgence dish – who doesn’t like fries? However, these are baked, not fried, and are immediately coated with a basil, garlic, and parmesan for a wonderfully aromatic side dish.

A huge thanks to Salt for Life for sponsoring this post. They’re having a fun contest going on, so head on over to their Instagram page to vote for your favorite!!! Salt For Life is a low sodium salt that has 75% less sodium than ordinary table salt, and it’s a 1-to-1 replacement, making it a simple transition from table salt. New England area folks, you can find this in DeMoulas Markt Basket and also select Walmart stores.

Mushroom Toast, Avocado Corn soup, Basil Shoestring Fries | bettysliu.comThe beauty of mushroom toast is that you can do whatever you want with it. I personally like juicy little beech mushrooms and thinly sliced king oyster mushrooms. As you know from my obsession with king oyster bacon (see here and here), thinly sliced king oyster bacon sautéed crisps up to “bacon” in no time. It provides a natural almost smoky taste that does wonders for any sort of topping. You can use shiitakes, button mushrooms, hen of the woods – any mushroom that strikes your fancy. One key part is to sauté the mushrooms without allowing them to steam. It’s a quick sear, and then the mushrooms are braised in broth. I also include scallions, both cooked and as a garnish. A tablespoon of yogurt is stirred in after the mushrooms are cooked, giving it a thicker sauce-like consistency.

Toasted sourdough bread slices
3 tbsp extra virgin olive oil
2 cups mushroom
freshly ground black pepper
1/4 cup water or chicken broth
red pepper flakes
2 stalks scallions, chopped, with white-green parts sliced thinly for garnish
1 tbsp greek yogurt  (can omit if wanted)

Heat a cast iron skillet over medium high heat. Add olive oil and let it heat up. Add mushrooms in batches, making sure no overlap occurs. Cook without stirring for about 3 minutes. Mushrooms should sear and become deep golden brown. Flip them and sear other side for 1-2 minutes.

Add chopped scallions and season with salt and pepper. Add in ¼ cup broth and cook until reduced by half, about 2-3 minutes. Turn off heat, then stir in greek yogurt. Spoon over toast. Top with reserved scallion and red pepper flakes.

A pale green soup with naturally thick consistency, this soup is so refreshing and light, with a kick of heat with every bite. The serrano pepper is optional, but I love it! No heavy cream or sour cream is added. Instead, avocado contributes not only the green tint but also the creamy thick texture of the soup.

2 ripe avocados, pitted and diced
3 cups water or stock
2 tbsp olive oil
kernels from 2 ears of corn (or 1.5 cups frozen corn kernels, with some reserved for garnish)
1 garlic clove, smashed
1.5 tsp salt for life
1 cup chopped white onion
1 fresh serrano chile, coarsely chopped
juice of 1 lime

Heat oil in a saucepan. Add in and onions and cook for 5-7 minutes, until soft and translucent. Add in garlic and corn. Add broth. Bring to a boil then reduce to a simmer. Cook for 10-15 minutes.

Pour into the container of a blender. Add serrano pepper and blend. Strain through a fine-mesh sieve.

Return broth to blender and add avocados and lime juice in. Blend again, then either chill or serve immediately. Garnish with sautéed corn, and dots of olive oil.

Crunchy yet soft, these fries are a wonderful side dish to this meal. Use a mandolin (or, if you’re like me and are intimidated by mandolins, use a sharp knife and cut a potato into matchsticks) to create matchsticks. Toss with minimal olive oil, spread them on a baking sheet lined with parchment paper, making sure to give the fires room – don’t let them overlap!! Then bake. I did two batches to make sure there was just a single layer. The tricky part is to keep an eye on the fries. My oven is pretty inconsistent and uneven, so half of my fries turned brown and crispy fast. They weren’t burnt, but they were mostly crunchy without any softness within. Just keep an eye on them and remove any that have turned golden brown already. Immediately after baking, toss with basil, garlic, and some parmesan cheese.

1 russet potato
2 tbsp olive oil
2 cloves minced garlic
1 tsp finely chopped basil leaves
3 tbsp finely grated parmesan cheese
freshly ground black pepper

Preheat oven to 425F. Line 2 baking sheets with parchment paper

Scrub potatoes, and dry. Cut using mandolin or sharp knife into matchsticks. Toss in a bowl with olive oil.

In a separate bowl, prepare basil, garlic, and parmesan. Set aside.

Separate matchsticks onto the two baking sheets in a single layer, with no overlapping of fries. Bake for 15 minutes. Remove any fries that have already turned golden brown. Flip fries, and then place back in. Switch racks – if the first baking sheet was on the top rack, move it to the bottom rack, and vice versa. Bake for another 5 minutes, keeping an eye on how brown they are. If there are any approaching burnt, remove. Bake another 5 minutes. Continue until all the fries are cooked.

Immediately toss with basil, garlic, and parmesan.

    Oh Betty, this looks so divine. I’m going to make mushroom toast and avocado corn soup for a friend who is coming for lunch today. Can’t wait to make the soup again once we have wonderful fresh Summer corn to work with! Thanks for the timely inspiration — I think the fries will have to wait for dinner tonight :)ReplyCancel

  • the mushroom toast sounds amazing! i love sauteed mushrooms (most of the time i enjoy the side mushrooms more than the main protein at steakhouses, oops), and piling them on top of crispy sourdough seems heavenly.ReplyCancel

  • Wait so, you’re saying I can bake shoestring fries??? Breaking out the mandolin this weekend!ReplyCancel

  • Betty this looks amazing! I first had mushroom toast in Vermont at this amazing restaurant called Hen of the Wood. They even topped it with a poached egg! Love your version here and the avocado corn soup to pair it with! <3ReplyCancel

  • I’ll take all three, please!! Loving the sound of those shoestring fries. Seriously drooling rn.ReplyCancel

  • As you probably know, I’m so into anything “toast” (especially sourdough). Will definitely give these a try, the look and sound delicious!ReplyCancel

  • Betty! You have such a gift for making things look beautiful. This whole meal is a total delight! That mushroom toast is giving me major cravings right now, must get myself some mushrooms soon!ReplyCancel

  • All of this looks so good and I love your use of the mushrooms here. Those fries are so perfect and your photography is just stunning as always. These recipes are simple, yet thoughtful and I love the notion of reducing salt and letting flavors speak for themselves. Be well! xoReplyCancel

  • Betty! I love how you based this on your go-to college meal – pesto gouda grilled cheese with roasted tomato soup is my favourite version at the moment. And mushrooms – I need to start visiting some farmers markets to try and get my hands on some more interesting mushroom varieties. They are such a gorgeous toast topping! xReplyCancel

  • Ohhhh Betty Betty Betty….this just looks to die for and so very unique!!! I found myself doing that whole geek-in-the-back-of-your-neck-heavily-gurgly-breathing at the description of this meal. What can I say? I’m very carefree sometimes (or careless) and don’t even realize what I’m doing. ^_^ I’ve had those sinful go-to college meals in the past and it’s not pretty! In case you’re really curious, one whole bahn mi Lee’s sandwich, a few manjoo bites, followed by an entire fresh, hot Lee’s baguette. 0_0 That was me for a few months after I started to come out of the sin called eating disorder.ReplyCancel
