This low carb pepper sauce recipe makes 4 serves. 1 serving is ¼ cup. Place a saucepan over high heat, add the butter and onion and saute until translucent. Add the beef stock and reduce by half a cup. Pour in the cream and add the three types of pepper and simmer for 5-7 minutes.
In a saucepan over medium heat, add the oil. When the oil starts to shimmer add the onions and banana peppers and cook for 3-4 minutes. Add in the garlic, stir and cook for 2 minutes. Next add in the tomato paste, stir to incorporate and cook for 3-5 minutes or until you can “smell” the tomato paste start to warm up.
Stir in the tomato puree and banana peppers. In low heat, cook for 30 minutes or until it thickens, by stirring occasionally. Now combine the rest of the ingredients. Cook for 2 minutes. If you prefer to have smooth and silky texture, use a hand blender.
Pour the marinara in the slow cooker crock, then layer the banana peppers in the slow cooker. Cover and slow cook on low for 5-6 hours. Sprinkle with cheese and cover again for 10 minutes until the cheese has melted. What other peppers can I use to make this low carb and gluten-free recipe?
