Place all the meatball ingredients into a big bowl.
Work everything together by hand.
Make walnut sized meatballs. If the meatballs doesn't seem firm enough place them into the fridge for an hour or two and quickly rework them before frying.
Brown the meatballs on medium to high heat on all sides.
If short on time just finish them off in the frying pan.
Add browned meatballs to an ovenproof dish, cover and bake them in a 350°F / 180°C oven for about 30 minutes.
Cream sauce
On medium heat melt butter in a pan.
Whisk in the rest of the ingredients one after the other. Only start adding the next ingredient once we have a completely worked the previous one into the sauce.
When all the ingredients are in, lower the heat and simmer until the sauce thickens. Mind that it will thicken further up as it cools. The keto variety will be like butter in the fridge.
