What cut of beef is best for beef and veggie soup?
Chuck roast is the sweet spot because it gets tender and flavorful with simmering. Look for well-marbled chuck, cut it into 1-inch cubes, and trim only the big tough pieces of fat. If the surface looks a little greasy after simmering, you can skim off extra fat with a spoon.
Can I make this in a slow cooker?
Yes. Brown the beef first if you can (worth it), then add everything except peas and green beans to the slow cooker. Cook on low 7 to 8 hours or high 4 to 5 hours. Timing varies a bit by slow cooker and how big your beef cubes are, so give it a tenderness check near the end. Stir in peas and green beans for the last 20 to 30 minutes.
Can I make this in an Instant Pot?
Yep. Use Sauté to brown the beef in batches, then sauté the aromatics and tomato paste. Pressure cook on High for 30 minutes with a 10 minute natural release. If the beef is not fork-tender (it should shred with pressure and have no chew), lock the lid back on and cook 5 to 10 minutes more on High. Add peas and green beans after pressure cooking and let them warm through on Sauté for a few minutes.
How do I thicken the soup?
Two easy options: mash a few potato chunks against the side of the pot and stir them in, or simmer uncovered for 10 to 15 minutes. If you want it more stew-like, mix 1 tablespoon cornstarch with 2 tablespoons cold water, stir in, and simmer 2 to 3 minutes.
How do I make it taste less bland?
Add salt in stages and finish with something bright. My go-to is 1 to 2 teaspoons apple cider vinegar or a squeeze of lemon at the end. Also check your broth. Some brands are shy on seasoning.
