Oma's German Spaghetti Beef (Print Version)

# Ingredients:

→ Main

01 - 450 grams ground sirloin
02 - 120 grams yellow onion, diced
03 - 120 grams celery, diced
04 - 400 grams diced tomatoes, canned or fresh
05 - 56 grams butter (divided, approximately 4 tablespoons)
06 - 5 grams salt (approximately 1 teaspoon)
07 - 0.5 grams ground black pepper (approximately 1/4 teaspoon)
08 - 450 grams spaghetti, cooked

# Instructions:

01 - Gently cook the diced onions in 14 grams of butter over low heat until just translucent, ensuring they remain white and do not caramelize.
02 - Increase heat to medium-high, add ground sirloin, salt, and black pepper to the onions, and cook until the beef is browned, tasting for seasoning and adjusting salt as needed.
03 - Stir in diced tomatoes and celery, cover with a lid, and simmer on medium-low heat until the celery is softened, about 15 to 20 minutes.
04 - Turn off the heat, mix in the remaining butter to enrich the sauce, then spoon over freshly cooked spaghetti and serve immediately.

# Notes:

01 - For best texture, avoid overcooking the onions; they should be softened but not brown.
02 - Sauce can be frozen in an airtight container and reheated for later meals.
03 - Garnish with freshly grated parmesan cheese for added flavor.
