This is a one-skillet hash of ground beef, yellow squash, zucchini, onion, garlic, and Roma tomatoes seasoned with smoked paprika and thyme. It comes together in about 55 minutes and uses a single pan, which means less cleanup and a fridge full of ready portions for the week ahead. If you have summer squash sitting on the counter and a pound of ground beef in the fridge, this is the most practical thing you can do with both.
The technique that matters
Two things make or break this hash. First, brown the beef properly — spread it in the pan and leave it alone for a minute or two before breaking it up. That contact with the hot surface builds the savory fond that flavors everything else. Second, when the squash goes in, resist stirring it constantly. Let it sit undisturbed long enough to pick up some color on at least one side. Squash releases a lot of water, and if you keep moving it around, it steams instead of browning and you end up with a soft, watery texture rather than tender pieces with a little bite. Skip crowding the pan — if your skillet is under 12 inches, cook the squash in two batches. A cast-iron or stainless skillet holds heat better than nonstick here, which helps both the beef and the squash get actual color instead of just cooking through.
Common problems and fixes
- Hash turns watery by the time it hits the table: Roma tomatoes add moisture late in the cook. If the mixture looks loose, turn the heat up slightly and cook uncovered for an extra 2–3 minutes to drive off the excess liquid before serving or portioning.
- Squash goes mushy before the beef is fully cooked: Add the squash and zucchini after the beef is already cooked through and the onions are soft. The squash only needs 5–7 minutes — it does not need to go in early.
- Spices taste flat or dusty: Bloom smoked paprika and thyme directly in the pan for 30–45 seconds before adding the tomatoes. Dry spices need brief heat contact with fat to open up; adding them to wet ingredients straight away mutes the flavor.
- Beef fat makes the finished dish greasy: After browning 80/20 beef, tip the skillet and spoon out excess rendered fat, leaving roughly a tablespoon behind. This keeps the hash rich without being oily, especially important if you are portioning it into containers for later.
- Garlic burns before the onions soften: Add garlic about halfway through sautéing the onions, not at the start. Onions need several minutes; garlic needs under two. Adding both at the same time almost always scorches the garlic.
Make-ahead notes
This hash holds up well as a batch-cooked staple. Let it cool to room temperature, then refrigerate in airtight containers for up to 4 days — the flavors actually improve overnight as the spices settle in. For longer storage, freeze in individual portions for up to 2 months; thaw overnight in the fridge rather than on the counter. To reheat, a skillet over medium heat with a splash of water or broth works better than a microwave because it lets any excess moisture cook off and keeps the squash from turning to mush. Microwave reheating works in a pinch — cover loosely and use 50% power in 90-second intervals, stirring between each. Ground beef must reach 160°F (71°C) when originally cooked, and reheated portions should hit that same temperature before eating.
Savory Skillet Squash and Hamburger Hash
Ingredients
- 1 lb ground beef preferably 80/20 for flavor and moisture
- 2 cups yellow squash sliced into 1/4-inch rounds, preferably organic and firm
- 1 cup zucchini sliced into 1/4-inch rounds
- 1 medium yellow onion finely diced
- 3 cloves garlic minced
- 1 cup roma tomatoes deseeded and finely chopped
- 2 tbsp olive oil extra-virgin
- 1 tsp smoked paprika
- 1 tsp dried thyme
- ½ tsp crushed red pepper flakes optional, for heat
- ½ tsp kosher salt or to taste
- ¼ tsp black pepper freshly cracked
- 2 tbsp fresh parsley chopped, for garnish
Instructions
- In a large cast-iron or heavy-bottomed skillet, heat 1 tablespoon of olive oil over medium heat (about 350°F / 175°C). Add the ground beef, breaking it apart with a wooden spoon. Cook for 6–8 minutes until browned and no longer pink. Drain excess fat if desired.
- Push the beef to one side of the pan. Add the remaining tablespoon of olive oil and sauté the diced onions for 3–4 minutes until translucent. Add the garlic and cook for an additional 1 minute until fragrant.
- Add the sliced squash and zucchini. Cook for 6–8 minutes, stirring occasionally, until the vegetables soften slightly and gain a golden hue.
- Mix in chopped tomatoes, smoked paprika, thyme, red pepper flakes, salt, and black pepper. Stir everything together and allow it to simmer on medium-low heat for 10–12 minutes until vegetables are fully tender and juices have melded.
- Taste and adjust seasoning. Remove from heat and sprinkle chopped parsley over the top before serving.
Notes
- Substitute ground turkey or plant-based crumbles for a lighter or vegetarian option.
- Use a mandoline for even squash slicing.
- Add a pinch of cumin or coriander for a smokier depth.

Your questions, answered
Can I use any type of squash, or does it have to be yellow squash and zucchini?
Yellow crookneck squash and zucchini work best because they have similar moisture levels and cook at the same rate. Pattypan squash is a fine substitute. Denser squash like butternut or acorn will need to be cut smaller and given a few extra minutes in the pan, and they will change the flavor profile noticeably toward something sweeter and starchier.
Is 80/20 ground beef required, or can I use leaner beef?
Leaner beef like 90/10 works fine, but you will need to add a tablespoon of olive oil to the pan before browning since there will not be enough rendered fat to sauté the onions and garlic afterward. The hash will be slightly less rich, which is a reasonable trade-off if that is what you have.
How do I know the ground beef is fully cooked without a thermometer?
Ground beef is cooked through at 160°F (71°C) — use an instant-read thermometer if you have one, because it is the only reliable method. If you do not have one, look for no remaining pink anywhere in the meat and juices that run clear, but a thermometer is a worthwhile $10 investment for any ground meat dish.
