When the ground beef and onion soften in the Dutch oven, the smell shifts from plain browned meat to something that already hints at taco night. That first stretch builds a savory base before the broth goes in, and it gives this taco soup with black beans its hearty feel without a long list of extra prep. I like how the tomatoes and green chiles join the beans and corn in the same pot; each spoonful gets a little of everything instead of leaving all the good bits at the bottom. The soup stays brothy, but it eats like a full meal.
The finished bowl has a nice contrast: tender black beans, sweet corn, and beef in a savory broth with a mild peppery note from the green chiles. The two seasoning packets give the soup its familiar taco-and-ranch character, while the tomatoes keep the broth from tasting one-note. Once the ingredients have had time together in the pot, you get a spoonful that’s hearty without turning thick or heavy.
Kitchen Note
With 90% lean beef, I check the pan before draining rather than doing it automatically. Pour off excess grease only if there’s a visible pool; this lean beef may not leave much behind.

Why the Seasoning Needs to Hit the Beef Before the Broth
Both seasoning packets go into the pot while the beef and onion are still warm, before the tomatoes and broth arrive. That order gives the dry seasoning a chance to cling to the meat and softened onion instead of landing in a full Dutch oven of liquid, where it can be harder to distribute evenly. Once the broth goes in, it carries those flavors through the beans, corn, and tomatoes.
Taco seasoning and ranch seasoning bring different things to the pot. The taco blend sets the familiar direction, while the ranch mix adds its own savory, herby note. Together, they make a fuller base than either packet would on its own. The broth is the carrier, not the main event, so the goal is an evenly seasoned soup where the beef and vegetables taste connected rather than separate.
The Canned Ingredients That Shape Every Spoonful
- Ground beef — The 90% lean blend keeps the soup meaty without leaving a lot of grease to remove. If you have 80/20 beef, it works too; drain the excess grease after browning, and expect a slightly richer finish.
- Yellow onion — It softens into the beef and gives the base a mellow savory note. A chopped white onion works in its place; it brings a slightly sharper flavor but softens in the same way.
- Taco and ranch seasoning — These packets are the quickest way to get the two distinct seasonings into the soup. Store brands work well; if you switch brands, use the same type and size of packet so the balance stays close.
- Diced tomatoes and green chiles — Canned tomatoes bring both tomato flavor and their canning liquid, while the chiles add a mild peppery edge. Fire-roasted diced tomatoes can replace regular diced tomatoes for a smokier note; use a can of the same size.
- Black beans and corn — Drain and rinse the beans, and drain the corn, so the canning liquid doesn’t become part of the broth. Inexpensive canned versions work just fine here because their texture holds up in the simmer.
- Beef broth — It carries the seasoning through the pot, so choose a broth whose flavor you like. A boxed broth is convenient; vegetable broth is the useful swap when making the meatless version.
How the Beef, Seasoning, and Broth Come Together
Brown the Beef and Soften the Onion
Set a 5-quart Dutch oven over medium-high heat and add the ground beef and chopped onion. Break the beef into small pieces as it cooks so it browns evenly rather than staying in large clumps. This takes 7 to 9 minutes; look for softened onion and beef that has reached 160°F. Check for excess grease before moving on.
Coat the Beef Before Adding the Cans
Stir the taco seasoning and ranch seasoning into the beef and onion first. Then add the diced tomatoes, green chiles, drained and rinsed black beans, drained corn, and beef broth. Stir until the ingredients are spread through the pot, taking care to bring beans and corn up from the bottom rather than leaving them in a layer. The tomato liquid goes in with the tomatoes.
Keep the Simmer Gentle and Uncovered
Raise the heat to high and bring the soup to a boil, then reduce the heat until you have a gentle simmer. Leave the pot uncovered and cook for 20 minutes, stirring occasionally. Look for small, steady bubbles rather than a hard rolling boil. The broth should stay clear and spoonable, with the beans and corn still easy to distinguish.
Three Swaps That Give This Pot a Different Spin
Make It Vegetarian With Plant-Based Crumbles
Replace the ground beef with plant-based ground crumbles and use vegetable broth instead of beef broth. Choose vegetarian versions of the taco and ranch seasoning mixes, then cook the crumbles with the onion according to their package guidance before adding the other ingredients. The soup loses the beefy depth but keeps its taco-ranch seasoning and hearty beans and corn.
Trade the Black Beans for Pinto Beans
Use a 15-ounce can of pinto beans in place of the black beans, draining and rinsing them before they go into the pot. Pinto beans are softer and creamier, so the broth feels a little fuller while the soup keeps the same overall character.
Turn Up the Heat With Spicy Taco Seasoning
Swap the regular taco seasoning packet for a same-size hot or spicy taco seasoning packet and leave the ranch seasoning as it is. That gives the broth more warmth without adding another ingredient or changing the cooking method. The heat level will depend on the brand, so this is the easiest adjustment if you want a bolder bowl.
Storage and Reheating
- Refrigerator: Cool leftovers promptly and refrigerate within 2 hours. Store in an airtight container for 3 to 4 days; the beans will soften a little as they sit.
- Freezer: Freeze in airtight portions for up to 3 months. Thaw overnight in the refrigerator; the beans may be softer after thawing.
- Reheating: Warm on the stovetop over medium heat, stirring until the soup reaches 165°F. For the microwave, cover the bowl and heat in intervals, stirring between them; a hard boil can make the beans break down.
