7-Grain Homemade Hamburger Buns (Bread Machine)

Make your sandwiches memorable with these homemade seven-grain hamburger buns topped with a variety of seeds.

Although designed for a bread machine, this recipe can be made in a stand mixer or by hand. See the directions in the recipe note.

Recipe Inspiration

When my sister and her husband from Denver came to town to watch the Rockies play against the Rangers earlier this summer, I prepared a meal to eat at the game including barbecue sandwiches made with homemade buns.

Weeks later, my husband is still raving about those buns and requesting a repeat performance. That’s how homemade buns can make a sandwich memorable.

As usual, I mix the dough for this recipe in my bread machine.  I DON’T BAKE IT IN THERE, just mix and knead the dough.

You might try it if you have a bread machine and/or delight in eating homemade bread that is perfectly mixed and kneaded with little effort and time on your part.

If you are a new bread-machine user or somebody who thought they didn’t like bread machines, please check out my previous posts about using a bread machine. You can also use a stand mixer or make this recipe by hand.

What is “7-grain mix”?

Don’t let the 7-grain mix scare you away. Substitute the same amount of bread flour, whole wheat flour, or wheat bran if you prefer. I buy Bob’s Red Mill 7 Grain Hot Cereal, containing wheat, rye, triticale, oats, oat bran, barley, rice, and flaxseed. 

It’s not always easy to find. Try Target, Whole Foods, or any grocery store with an organic food section (See the link below to order online.) This recipe is a variation on my Potato-Cheese Rolls which I love because the rolls naturally stay fresh longer because of the potatoes.

Kitchen secret for the mashed potatoes:

This comes in handy for hamburger buns because you can make them ahead. I like to use leftover mashed potatoes as opposed to difficult-to-find potato flour or bland-tasting instant potatoes. The salt, pepper, butter, and milk added when making everyday mashed potatoes seems to make these rolls even better.

Because I tend toward spur-of-the-moment baking, I freeze any leftover mashed potatoes passing through my kitchen into half-cup portions as seen in the picture above. They only need to defrost in the microwave before they go into my bread machine.

P.S. If you need a quick lesson in making perfect dough balls, see this video.

    Yield: 8 buns

    7-Grain Hamburger Buns

    7-Grain Homemade Hamburger Buns (Bread Machine)

    Make these 7-grain buns for your next cookout or tailgate.

    Prep Time 2 hours 30 minutes
    Cook Time 20 minutes
    Total Time 2 hours 50 minutes



    • 1 egg
    • 2 tablespoons sugar
    • 1 teaspoon salt
    • 1/4 cup butter cut into small pieces
    • 1/2 cup well-seasoned mashed potatoes
    • 2/3 cup milk
    • 2-1/2 cups bread flour
    • 1/2 cup 7-grain mix (or use wheat bran or whole wheat, if preferred)
    • 2 teaspoons bread machine yeast


    • 1 egg
    • 1 tablespoon water
    • Poppy seeds and sesame seeds


    1. Add egg, sugar, salt, butter, and mashed potatoes to bread-machine pan.
    2. Heat milk 1 minute and 30 seconds in microwave on HIGH. Pour over other ingredients already in the bread machine to warm them and melt the butter.
    3. Add bread flour and then yeast.
    4. Select the dough cycle and start.
    5. When finished, remove dough from pan to floured surface. Divide into 8 portions and form into balls. Allow to rise until double.
    6. Flatten balls with palm of your hand, rather severely, or else your buns will be too thick in the middle.
    7. Make glaze by whisking egg and water together in a small bowl. Carefully brush tops and sides of buns. Sprinkle with poppy seeds and sesame seeds.
    8. Bake in preheated 375 degree oven for 15-20 minutes or until golden brown and internal temperature reaches 190 degrees.


    Vary the seeds on top according to what you like and/or have on hand. Or, leave them off if you prefer. I like to make some with, and some without to please all the eaters around my table.

    How much potato flour do I have to use instead of using mashed potatoes?


    Tuesday 8th of September 2020

    This is from the King Arthur website as I have not tried this myself.

    "How to do it: Substitute 3/4 cup unseasoned mashed potatoes for every 1/4 cup potato flour called for in your recipe. Reduce any added liquid in the recipe by 50%, subsequently adding more flour or liquid if necessary to make a soft but not overly sticky dough."

    Great recipe I made these today for pulled pork sandwiches - they came out nicely. I did have potato flour on hand so I used it instead of mashed potatoes.

    Good to know that potato flour will work instead. I will try that myself. Thanks for writing.

    Hi Paula, I'am thinking of making these buns. But, in the recipe, you divide the dough into 8 pieces. Then, roll into balls. you make the balls the same as you do your dinner rolls? If so, when you flatten the balls, how flat should they be? I don't want them toooooo thick. I guess I could just use, trail and error. I've also, made same of you bread and loved it all. Thanks

    Hi Liz, I would flatten them to the size of a small hamburger bun you would buy at the store. After a time or two, you will know how much to flatten them. They will rise a lot so I would flatten to about 1/2 inch.

    Hey! It's just the recipe I was looking for. Quick question, if I don't want to use potatoes what would be a good substitute? I am avoiding potato due inflammation reasons. I know this post is older, but am crossing my fingers for a reply. Thanks!

    Dear Paula, I just made them. They were perfect.
