Ingredients

🥖 Artisan Sourdough Bread

This hearty base provides fiber, protein, and complex carbs. The natural fermentation in sourdough may also support digestion. Using a whole grain or multigrain variety adds extra texture and nutrients from seeds and whole grains.

🥑 Avocado

Creamy and rich, avocado adds heart-healthy monounsaturated fats, potassium, and fiber. It also balances the strong flavor of natto and helps bind everything together on the toast.

🍱 Natto

Natto is a traditional Japanese fermented soybean dish loaded with probiotics, especially Bacillus subtilis. It also contains vitamin K2, which supports bone and heart health, along with protein, iron, and fiber. Its sticky texture and bold, pungent flavor make it a standout superfood for gut health. I order my natto from Nyrture in New York.

🌿 Nori Seaweed

Nori enhances the umami flavor and adds iodine, minerals, and antioxidants. It complements the natto beautifully and adds a subtle oceanic note.

🍋 Lemon Juice

Fresh lemon juice brightens the flavors and helps prevent the avocado from browning. It also supports digestion and is a source of vitamin C.

🧂 Everything Bagel Seasoning

This everything bagel seasoning blend—containing sesame seeds, poppy seeds, garlic, and onion—adds crunch, depth, and flavor complexity. It's the perfect savory topping that brings all the ingredients together. Salt to taste!

🔥 Optional: Sriracha

For those who like a bit of spice, sriracha adds heat and tanginess. A little goes a long way to enhance the overall flavor profile.

🌱 Optional: Microgreens

Add a handful of fresh microgreens like radish, broccoli, or sunflower for crunch, color, and a boost of antioxidants and phytonutrients.

Ingredients for natto avocado toast: sourdough multigrain bread, avocado, natto, nori seaweed, lemon, everything bagel seasoning and optional sriracha and microgreens.

Tips for Success

Choose a good-quality artisan sourdough whole grain or multigrain for both flavor and nutritional value.
Use a ripe avocado for the creamiest texture.
Select a high-quality natto. I love the Nyrture brand natto in New York. I get it delivered to my home a few times each month.
Customize toppings based on your spice tolerance and nutritional preferences. Add a splash of tamari or coconut aminos for a boost of umami goodness.

How to Prepare

Prepare the Nori: Using clean kitchen scissors, mince a quarter sheet of nori seaweed. Set it aside. You can also use nori flakes if you prefer.

Toast the Bread: Toast your sourdough multigrain bread in the toaster or toaster oven until golden and crisp. Set it aside.

Prepare the Avocado: Thinly slice the avocado while it's still in the skin. Then, use a spoon to scoop it out and place it on the toasted bread. Alternatively, you can mash the avocado in a bowl with the lemon juice and a pinch of salt (optional). My husband is a mash the avocado guy, and I'm a slice the avocado girl. Lol.

Add the Nori: Carefully sprinkle the nori evenly across the avocado toast.

Dollop the Natto: Add the natto to the avocado and nori toast. Evenly spread it across the toast with a spoon.

Add Toppings: Sprinkle everything bagel seasoning and drizzle with fresh lemon juice. If using, add microgreens and sriracha.

Enjoy immediately!

Frequently Asked Questions

Can you eat natto on toast?
