These cheeseburger zucchini boats are our favorite keto ground beef recipe! It's the perfect easy weeknight summer meal at roughly 4.5 net carbs per serving.
In a medium size skillet over medium heat, brown meat and and drain off any grease.
Add tomato paste, mustard, cream cheese, broth and spices. Stir well and let mixture simmer for 5-7 minutes, or until the cream cheese has melted and the mixture thickens.
Meanwhile, slice zucchini lengthwise and scoop out the center. (I find this easiest with a metal teaspoon)
Place zucchini boats on a large baking sheet and carefully spoon the cheeseburger mixture into the zucchini.
Top with cheese and bake 20-24 minutes until the zucchini is fork tender.
Notes
Cheese: Use Pepper Jack cheese for a spicy version!
Nutrition: Values are calculated for 3 FULL zucchini, but we hollow out the inside. This likely means the true carb and fiber count is a bit overstated in the values below.
