Best Ways to Enjoy It

Serve these steak bites hot right out of the skillet. They look amazing in a deep ceramic bowl with extra parsley.

Pair this with a light side salad or a drizzle of chimichurri. It is the perfect cozy dinner for a chilly fall evening.

If you are extra hungry, serve it over a bed of quinoa. The peppers add a fresh, sweet crunch that balances the savory steak.

Storage & Reheating

Store leftovers in airtight containers for up to four days. This makes your weekday lunches totally stress-free and nutritious.

Reheat in a skillet over medium heat to keep the steak tender. Avoid the microwave if you want to keep that perfect texture.

You can also freeze the steak and potatoes for up to a month. Just thaw in the fridge overnight before reheating.

Tips for Best Results

• Use different colored bell peppers for a beautiful presentation.

Ways to Switch It Up

• Swap sweet potatoes for butternut squash for a fall twist.

• Drizzle with a creamy garlic sauce before serving.
• Swap parsley for cilantro and add a squeeze of lime.

Common Questions

What is the best cut of steak to use?

Top sirloin is lean, affordable, and stays tender when cut into bites. You can also use ribeye or New York strip for more fat.

Can I make this in one pan?

You can roast everything on a sheet pan if you prefer. Just add the steak and peppers during the last 10 minutes.

How do I know when the steak is done?

The steak bites should be browned on all sides and slightly firm. They usually reach medium-rare in about 5-6 minutes total.

Stop waiting and start cooking—you deserve a meal this good!
