How to Make
Quick Overview
Craving something quick, hearty, and full of flavor? This recipe is surprisingly easy and rewarding. With minimal prep—just slicing some beef and onions—and a single skillet, you can have a satisfying, crowd-pleasing meal in about 30 minutes. The caramelized onions provide a hint of sweetness, while fresh thyme and garlic add depth. It’s perfect for both busy weeknights and leisurely Sunday suppers.
Ingredients
- 1 lb beef (such as flank steak or sirloin), sliced into thin strips
- 2 large onions, thinly sliced
- 3 cloves garlic, minced
- 2 tablespoons olive oil
- 2 sprigs fresh thyme
- Salt and pepper to taste
Step-by-Step
- Prepare the Ingredients:
Begin by slicing your beef into thin strips against the grain for maximum tenderness. Peel and thinly slice the onions, and mince the garlic. - Caramelize the Onions:
Heat one tablespoon of olive oil in a large skillet over medium heat. Add the sliced onions along with a pinch of salt. Cook, stirring occasionally, for about 10-15 minutes, or until the onions are soft and golden brown. If they start to stick, add a splash of water to deglaze the pan. - Sauté the Garlic:
Add the minced garlic to the caramelized onions and cook for another minute, stirring gently so the garlic becomes fragrant but doesn’t burn. - Cook the Beef:
Push the onions to the edge of the skillet or remove them temporarily and add the remaining tablespoon of olive oil. Turn the heat up to medium-high and add the beef strips in a single layer. Season generously with salt and pepper. Sear the beef for about 2-3 minutes on each side, until browned and just cooked through. - Combine and Finish:
Return the onions (if removed) to the skillet with the beef. Toss everything together, add the thyme sprigs, and cook for an additional minute so all the flavors come together. Taste and adjust seasoning as needed. Remove thyme before serving. - Serve and Enjoy:
Transfer to a serving platter or individual plates. Serve hot, with your favorite sides.
What to Serve Tender Beef Strips Sautéed with Caramelized Onions With
This comforting dish pairs beautifully with a variety of sides. For a classic approach, serve it over buttery mashed potatoes or steamed white rice to soak up all those rich flavors. For a lighter meal, a crisp green salad or simple steamed vegetables adds balance and color to your plate. Fresh baguette slices are perfect for mopping up every bit of savory sauce. Round out your meal with a glass of dry red wine or a sparkling lemonade for a refreshing contrast.
Top Tips for Perfecting
- Choose the Right Cut:
Flank steak or sirloin works best for this recipe, as they cook quickly and stay tender. Make sure to slice against the grain for extra softness. - Take Your Time with the Onions:
Low and slow is key for caramelizing. Don’t rush this step—good onions are worth it! - Adjust the Seasonings:
A splash of Worcestershire sauce or a hint of balsamic vinegar can add an extra layer of flavor, if desired. - Don’t Overcrowd the Pan:
Cook the beef in batches if necessary to ensure it browns properly instead of steaming. - Substitutions:
Swap thyme for rosemary, or use ghee instead of olive oil for a richer taste. You can also experiment with adding mushrooms or bell peppers.
Storing and Reheating Tips
To store leftovers, let the beef and onions cool completely, then transfer to an airtight container and refrigerate for up to 3 days. To reheat, place the mixture in a skillet over medium-low heat until warmed through, or microwave in short bursts, stirring occasionally. For freezing, pack the cooked beef and onions in freezer-safe bags, remove as much air as possible, and freeze for up to 2 months. Thaw overnight in the fridge before reheating. For best results, avoid overcooking during reheating; this will keep the beef tender.
FAQs
Can I use a different cut of beef?
Absolutely! Flank steak, skirt steak, sirloin, or even tenderloin work beautifully.
How long does it take to caramelize onions?
For deep golden caramelization, give onions at least 10-15 minutes over medium heat, stirring now and then.
Can I make this recipe ahead of time?
Yes! The flavors get even better after sitting, so feel free to make a day in advance and reheat gently before serving.
Do I have to use fresh thyme?
No worries if you don’t have fresh thyme—dried thyme works too. Use half the amount, as dried herbs are more concentrated.
Is this recipe gluten-free?
Yes, as written, it’s naturally gluten-free. Just double-check all your ingredients, especially if you add sauces or side dishes.
