High protein granola.

Granola is always a huge hit at my house. My boys love stirring it into yogurt, my husband loves snacking on it at work, and I love sprinkling it on top of my smoothies. Since my family loves it so much, I set out on a mission to create a high-protein version filled with whole grain oats, hearty nuts, crunchy seeds, and protein powder. And I’m pleased with the result of my High Protein Homemade Granola for you to try!


  • Oats: High in protein and fiber, oats roast wonderfully to be crunchy and delicious in many breakfast foods.
  • Walnuts: I use walnuts because they’re a personal favorite, but you could use pecans, cashews, or hazelnuts as well.
  • Pumpkin seeds: Rich in vitamins and minerals, and much easier to eat in their raw form, they add a nice change in texture to the granola.
  • Flaxseed meal: Flavorless, but adds omega 3s and fiber to the granola.
  • Protein powder: Packs in the punch to help keep you full and satisfied until lunch.
  • Cinnamon: Sweetens as well as adds loads of anti-oxidants.
  • Salt: Just a pinch, but it helps balance out the flavors and sweetness.
  • Honey: Naturally sweetens the granola without adding a ton of processed sugar.
  • Olive oil: Helps the granola roast and get nice and crunchy in the oven.

  1. This is quite delicious! I used a collagen protein powder and local honey (allergies) and it is SO yummy. So glad to know about this recipe — will be making this again and again.

  2. This is such a fabulous recipe to either follow to-the-letter or make substitutions. I just made a batch using pistachio oil and date syrup (in place of the olive oil and honey) and added an extra raw egg white to the mixture to make it more “clumpy” before putting it in the oven :) absolutely delicious! Thank you!

  3. How much would you suspect in in a single serving size? I might have missed it. Turned out very good though. Thanks for sharing.

  4. i like the recipe but it contains oat and nuts and protein powder it isnt possible that contains 5 gr protein or it isnt high protein recipe there is a mistake!!!!

  5. I LOVES this granola and every time I make it I get either asked for more or the recipe. I love how flexible it is and I make it gluten free as well. So good. I use coconut oil and maple syrup and it’s just the right of sweetness and healthy! I usually add extra fluid to make bars. I won’t use another recipe any more! Thanks!

  6. I’ve never left a comment on a recipe online before (I usually just lurk and then credit the creator if I post a photo on IG) but this granola was SO GOOD I had to comment! I used a vanilla toffee flavor pea protein powder and maple syrup instead of honey to make it vegan but otherwise left everything the same. It cooked in 25 minutes. When it came out I absolutely could not stop snacking on it. I can see this being my new go-to granola recipe! By the way, I shared a picture on my IG and tagged you, @abigaillee_runs. Thanks for the great recipe!

  7. This is just what I was looking for! It was delicious! I did not have pumpkin seeds, so I used pecans instead! It was soooo good. I am glad you mentioned to start watching it at 20 minutes because mine was done at 22 minutes! Thank you for this wonderfully easy recipe!

    1. You added protein powder, but still your recipe cannot honestly be considered “high protein” when only 10 percent of the calories are from protein.

  8. Just put my second batch this month in the oven. It’s addictive. I used coconut oil and it’s great!!
    I have a ton of pecans in my freezer so I used those instead of almonds.
    It’s delish with plain greek yogurt and berries.
    Thanks for sharing!

  9. Awesome recipe. However, 30 minutes over-cooked my batch. I’d check it at 15 minutes then watch closely from there.

  10. Looks so delicious! I was just looking for a granola recipe and saw this on your Instagram! I’m going to try this for next week. Do you know what the serving size is, or am I just missing it? Thanks for all the awesome recipes!

      1. Fabulous receipe I actually make a similar granola with protein powder and I use coconut oil and maple syrup, I add in freeze dried raspberry, flaked almonds and coconut flakes at the end. Before placing in the oven I flatten with back of spoon to create clusters (don’t stir half way through and just keep an eye on it) I bake for 15 mins at 160°c but everyone’s ovens are different. How long does your granola keep for? I find it lasts longer with no added protein
