Ingredients
• For the Keto Psyllium Buns
• 1 ¼ cups / 140g (4.9 oz) almond flour
• 5 tbsp / 45g (1.59 oz) ground psyllium husk powder
• 2 tsp baking powder
• 1 tsp (5 ml) sea salt
• 3 large egg whites
• 2 tsp apple cider vinegar
• 1 ¼ cups / 300ml boiling water
• For the Savory Meat Sauce
• 2 tbsp / 30ml olive oil
• 1 ½ lbs / 680g (24 oz) ground beef
• 1 yellow onion, chopped
• 4 garlic cloves, minced
• 1 can (14 oz / 400g) crushed tomatoes
• 4 tbsp / 60g (2.12 oz) tomato paste
• 1 tbsp chili powder
• 1 tbsp ground mustard
• 1 tbsp (15 ml) red wine vinegar
• 2 tsp salt
• ¼ tsp ground black pepper
• For Assembling
• ½ cup / 115g mayonnaise
• 6 oz / 170g shredded cheddar or mozzarella cheese
Instructions
1. First, prepare the buns. Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. In a large bowl, whisk together the almond flour, psyllium husk powder, baking powder, and sea salt.
3. Add the egg whites and apple cider vinegar to the dry , followed by the boiling water. Using a hand mixer or a sturdy whisk, mix thoroughly for about 30 seconds until the dough becomes thick and pliable.
4. Divide the dough into 6-8 equal portions and shape them into bun-like discs with wet hands to prevent sticking. Place them on the prepared baking sheet.
5. Bake on the middle rack for 50-60 minutes, or until firm to the touch and golden brown. Let them cool completely on a wire rack.
6. While the buns are baking, prepare the meat sauce. Heat the olive oil in a large skillet or Dutch oven over medium-high heat. Add the chopped onion and cook until softened, about 3-4 minutes. Add the minced garlic and cook for another minute until fragrant.
7. Add the ground beef to the skillet, breaking it up with a spoon. Cook until browned all over. Drain any excess grease.
8. Stir in the crushed tomatoes, tomato paste, chili powder, ground mustard, red wine vinegar, salt, and pepper. Bring the mixture to a boil, then reduce the heat to low.
9. Allow the sauce to simmer for at least 10-15 minutes, stirring occasionally, to allow the flavors to meld. Taste and adjust seasonings if necessary.
10. To serve, slice the cooled buns in half. Spoon a generous portion of the hot meat sauce onto the bottom buns, top with shredded cheese and a dollop of mayonnaise, and place the top bun on.

Pro Tips
• for Perfect Keto Sloppy Joes
• For a richer flavor, add a teaspoon of smoked paprika or a tablespoon of Worcestershire sauce to the meat mixture.
• After slicing the buns, lightly toast the cut sides in a dry pan or under the broiler for a minute to enhance their texture and sturdiness.
• The psyllium dough can be sticky. Keep a small bowl of water nearby to wet your hands, which makes shaping the buns much easier.
• The meat sauce tastes even better the next day! It’s a perfect make-ahead component for a quick weeknight dinner. Store it in an airtight container in the refrigerator for up to 4 days.
FAQ
Q: Are these Keto Sloppy Joes gluten-free
A: Yes, this recipe is completely gluten-free. The buns are made with almond flour and psyllium husk powder, and the meat sauce contains no gluten-based ingredients.
Q: Can I make the psyllium buns ahead of time
A: Absolutely. You can bake the psyllium buns in advance and store them in an airtight container at room temperature for up to 2 days. For the best texture, we recommend toasting them before serving.
Q: What can I use instead of homemade keto buns
A: If you prefer not to make the buns, you can serve the savory meat sauce over cauliflower rice, zucchini noodles, a bed of lettuce for a sloppy joe salad, or with your favorite store-bought keto-friendly bread.
Q: How do I store and reheat leftover sloppy joe meat
A: Store the leftover meat sauce in an airtight container in the refrigerator for up to 4 days. You can easily reheat it in a saucepan over medium-low heat or in the microwave until warmed through.
Pro Tips
- Keep a small bowl of water next to you while shaping the buns — the psyllium dough is sticky, and wet hands make clean, round discs that bake evenly.
- Mix the dough just until thick and pliable (about 30 seconds), then bake the buns a full 50-60 minutes until firm to the touch; psyllium needs the long bake to set the crumb instead of staying gummy.
- Let the buns cool completely on a wire rack before slicing, and toast the cut sides briefly in a dry pan — that little toast makes them sturdy enough to hold the saucy filling.
- Drain the excess grease off the browned beef before adding the crushed tomatoes and tomato paste, so the sauce stays rich and thick rather than oily.
- Simmer the meat sauce at least 10-15 minutes — and note it tastes even better the next day, so make it ahead and refrigerate for up to 4 days for quick weeknight assembly.
Frequently Asked Questions
Can I make the sloppy joe filling ahead of time?
Definitely — the meat sauce keeps in an airtight container in the fridge for up to 4 days and actually improves overnight. Reheat it gently while you toast the buns.
Can I freeze the psyllium husk buns?
Yes. Cool them completely, then freeze in a sealed bag for up to 2 months. Thaw at room temperature and refresh them in a warm oven or dry pan so the crumb firms up again.
What can I use instead of psyllium husk powder?
Psyllium is what gives these buns their bread-like structure, so there is no perfect swap; ground flax makes a denser, more fragile bun. Stick with the 5 tablespoons of psyllium for the soft-yet-sturdy result the recipe promises.
How do I keep the buns from falling apart under the filling?
Cool them fully and toast the cut sides before loading them up. A bun that is warm and soft straight from the oven will not hold the saucy beef as well as a toasted one.
