What makes this dish special is the balance: the beef is browned until deeply savory, the vegetables are cooked just until tender-crisp, and the sauce is bright and tangy without being heavy. It's the kind of meal that feels indulgent but is actually packed with nutrients.

Whether you're meal-prepping for the week or need a quick weeknight rescue, this skillet delivers. It's forgiving, flexible, and guaranteed to become a regular in your rotation.

About the Ingredients

1 lb (450g) lean ground beef (93% lean)

Lean ground beef keeps the dish light. For a richer flavor, use 85% lean and drain excess fat. You can also substitute ground turkey or chicken.

1 tbsp olive oil

Use a good quality extra-virgin olive oil. You can substitute avocado oil for a higher smoke point.

1 medium yellow onion, diced

Yellow onion adds sweetness. Use a sweet onion like Vidalia for a milder taste, or shallots for a more delicate flavor.

3 cloves garlic, minced

Fresh garlic is essential. If using jarred, use 1 tsp. For a milder garlic flavor, roast the cloves first.

1 medium zucchini, diced (about 1 cup)

Zucchini adds moisture and nutrients. If not in season, use yellow squash or diced eggplant.

1 red bell pepper, diced (about 1 cup)

Red bell pepper is sweet and colorful. Use any color, or substitute a poblano for a slight kick.

1 can (15 oz / 425g) diced tomatoes, with juices

Fire-roasted diced tomatoes add smoky depth. Use no-salt-added to control sodium, or fresh tomatoes (about 2 cups) in summer.

2 tbsp tomato paste

Concentrated umami. If you don't have it, skip it and add an extra 1/4 cup of diced tomatoes.

1 tsp dried oregano

Dried oregano is classic. Use 1 tbsp fresh if you have it. Marjoram is a good substitute.

1/2 tsp smoked paprika

Smoked paprika adds a subtle smokiness. Regular paprika works, or use a pinch of cayenne for heat.

1/2 tsp salt, plus more to taste

Kosher salt is best. Adjust to your preference, especially if using salted tomatoes.

1/4 tsp black pepper

Freshly ground black pepper adds a bite. Adjust to taste.

Tips & Tricks

• Don't overcrowd the pan when browning the beef: work in batches if needed to get a good sear.
• Dice vegetables uniformly so they cook evenly.
• If the skillet looks dry before adding tomatoes, add a splash of water or broth.

Step-by-Step Instructions

1. Brown the Beef

Heat olive oil in a large skillet over medium-high heat (375°F / 190°C). Add ground beef and cook, breaking it up with a spoon, until no longer pink and starting to brown, about 5-7 minutes. Season with salt and pepper. Use a slotted spoon to transfer to a plate, leaving any fat in the pan.

2. Sauté Aromatics

In the same skillet, add onion and cook over medium heat (350°F / 175°C) until translucent, about 3-4 minutes. Add garlic and cook for 30 seconds until fragrant.

3. Add Vegetables

Add zucchini and bell pepper. Cook, stirring occasionally, until they begin to soften but still have a slight crunch, about 4-5 minutes.

4. Incorporate Tomatoes and Seasonings

Return the beef to the skillet. Add diced tomatoes with their juices, tomato paste, oregano, and smoked paprika. Stir to combine.

5. Simmer the Skillet

Bring the mixture to a simmer, then reduce heat to medium-low (300°F / 150°C). Let it bubble gently, uncovered, for 10-12 minutes, stirring occasionally, until the sauce thickens slightly and the flavors meld. The vegetables should be tender but not mushy.

6. Adjust Seasoning

Taste and adjust salt and pepper as needed. If you like a bit of heat, add a pinch of red pepper flakes.

7. Serve and Garnish

Remove from heat. Serve hot, garnished with fresh parsley or basil if desired. Enjoy over rice, quinoa, or with crusty bread.

Delicious Variations

• Add 1 cup of cooked quinoa or brown rice to the skillet for a heartier meal.
• Stir in 1/2 cup of shredded cheddar or Monterey Jack during the last 2 minutes of simmering for a cheesy twist.
• Swap the zucchini and bell pepper for mushrooms and spinach for a different veggie combo.
