In a large skillet brown the ground beef until cooked all the way through. Drain any excess grease well from the beef. Place the cooked ground beef in the bottom of a slow cooker.: As the ground beef hits the hot pan you will hear an eager sizzle, and as it browns it will release a rich, roasted aroma that signals depth developing. Browning until the meat is evenly seared and no pink remains creates Maillard flavors that form the stew's backbone. Drain any excess grease carefully to avoid a greasy broth, and transfer the meat to the slow cooker so the browned bits stay concentrated in the meat rather than floating in the liquid. A common mistake is to skip proper browning which results in a flatter taste, or to overcrowd the pan which causes steaming instead of browning. Take your time in batches if needed, and scrape up the fond for extra flavor before adding the meat to the cooker.
Chop potatoes, carrots and onions into chunks that are about an inch big, small enough to fit on a spoon.: When you cut the potatoes , carrots , and onion into roughly uniform one inch pieces they will cook through at the same rate, giving a pleasant mosaic of textures in each spoonful. The potatoes will release a starchy scent as they are cut, the carrots a faint sweet root aroma, and the onion an aromatic sharpness that mellows as it softens. Too large and the vegetables can stay undercooked, too small and they may become mushy; aim for consistency for the best mouthfeel. A typical oversight is uneven chopping that leaves some pieces too hard while others disintegrate.
Add chopped potatoes, carrots, onion, garlic, beef broth, tomato paste, and diced tomatoes with the juice to the slow cooker. Add sugar, Italian seasoning, garlic salt, black pepper, and onion powder in the slow cooker.: As you layer the ingredients into the slow cooker the aromas begin to mingle, with the bright tomato scent melding into the savory broth and aromatic herbs. Stirring will distribute the concentrated tomato paste and seasoning so the flavors dissolve into the liquid, creating an even base. The beef broth carries the flavors into the potatoes and carrots , while the sugar tames the tomato acidity and the Italian seasoning lends herbal brightness. A common pitfall is adding too much salt early on; taste at the end and adjust if needed, since flavors concentrate as the stew reduces.
Stir everything in the slow cooker to combine, then cover the slow cooker.: Once everything is combined you will notice the steam beginning to rise as the cooker warms, and the mixture will take on a cohesive tomatoey color. Covering traps heat and moisture, ensuring the vegetables cook gently and the flavors marry. Leaving the lid off will lengthen cooking time and allow too much liquid to evaporate, potentially producing drier vegetables. If your slow cooker has a tight fitting lid, the steam will build and gently tenderize the ingredients into a harmonious stew.
Turn the slow cooker to low heat and cook for 6 hours. You can also cook on high heat for 4 hours. The potatoes will be fork-tender when finished. Scoop and enjoy!: Over the six hour low cook you will see the stew deepen in color and the aroma will fill your kitchen with a slow roasted tomato and beef scent. Low and slow yields a more integrated flavor where the potatoes and carrots become tender and the broth develops a rounded mouthfeel. If short on time, the high setting for four hours will still produce tender vegetables, though the flavor marriage may be slightly less cohesive. When the potatoes are fork tender and the broth is glossy and slightly thickened, the stew is done. A mistake to avoid is stirring excessively during the cook which can prolong the time needed to reach tenderness; instead let the cooker work undisturbed.
