Prep the vegetables: If using zucchini, grate it on the large holes of a box grater. Place in a clean kitchen towel and squeeze out as much liquid as possible.
If using riced cauliflower, steam lightly and squeeze dry. Less moisture = crispier patties.
Mix the base: In a large bowl, combine the sausage, shredded zucchini or cauliflower, cheddar, eggs, Parmesan, almond flour, onion powder, garlic powder, smoked paprika, and black pepper. Use your hands or a sturdy spatula to mix until just combined. Do not overwork.
Taste test for salt: Heat a small bit of oil in a skillet and pan-fry a teaspoon of the mixture.
Taste and adjust salt if needed before forming all the patties.
Form the patties: Divide the mixture into 8–10 equal portions. Press into flat rounds about 1/2 inch thick. Thinner patties crisp up more, but don’t make them flimsy.
Preheat the pan: Heat a large skillet over medium to medium-high heat.
Add 1–2 tablespoons oil. The pan is ready when a small crumble sizzles on contact.
Cook in batches: Add patties without crowding. Cook 4–5 minutes per side, until deep golden and crisp.
Reduce heat slightly if they brown too fast. Add more oil as needed for later batches.
Drain and rest: Transfer cooked patties to a wire rack or paper towels. Let them rest 3 minutes to set and finish crisping.
Serve: Top with a dollop of sour cream, a sprinkle of chives, and a fried egg if you like.
A splash of hot sauce or a side of sautéed greens is great, too.
