In a large pot, bring 4 cups of water to a boil. Add the steel-cut oats and simmer for about 20 minutes, stirring occasionally, until the oats are cooked and have absorbed most of the water.

In a separate skillet, cook the ground pork over medium heat until browned and cooked through. Make sure to break it up into small pieces as it cooks.

Add the chopped onion and minced garlic to the skillet with the cooked pork. Sauté for a few minutes until the onion becomes translucent.

Add the cooked oats to the skillet with the pork and onion mixture. Mix everything together.

Stir in the salt, black pepper, sage, thyme, nutmeg, and cloves. Make sure the spices are evenly distributed throughout the mixture.

Reduce the heat to low and cook the Goetta mixture for about 30-40 minutes, stirring occasionally, until it thickens and becomes cohesive.

Once the mixture has thickened, you can either shape it into a loaf or form it into patties. You can use a loaf pan or a baking dish lined with parchment paper if you're making a loaf.

Allow the Goetta to cool and set in the refrigerator for a few hours or overnight.

When you're ready to enjoy it, slice the Goetta into desired portions. You can pan-fry the slices until they are crispy and golden brown on both sides.

Serve the Goetta slices alongside your favorite breakfast dishes or in a breakfast sandwich. Enjoy!
