Preparation
To achieve the best results with our flat iron steak in crock pot recipe, proper preparation is essential. Focusing on seasoning the steak and prepping the vegetables ensures every bite bursts with flavor and tenderness.
Preparing the Flat Iron Steak
- Trim the Steak: Start by trimming any excess fat or silver skin from the flat iron steak. This step prevents unwanted chewiness and helps the seasonings penetrate the meat.
- Pat Dry: Use paper towels to thoroughly pat the steak dry. Removing moisture ensures a better sear and locks in the steak’s natural juices during slow cooking.
- Season Generously: In a small bowl, combine the following dry seasonings:
| Seasoning | Amount |
|---|---|
| Salt | 1 ½ teaspoons |
| Black Pepper | 1 teaspoon |
| Smoked Paprika | 1 teaspoon |
| Garlic Powder | 1 teaspoon |
| Onion Powder | 1 teaspoon |
| Crushed Red Pepper Flakes (optional) | ¼ teaspoon |
- Apply the Rub: Evenly coat both sides of the flat iron steak with the spice mixture. Use your hands to massage the seasonings for deeper flavor infusion.
- Sear the Steak (Optional but Recommended): Heat a tablespoon of oil in a skillet over medium-high heat. Sear the steak for 2 minutes on each side until browned. This step locks in flavor and creates a beautiful crust before slow cooking.
Preparing Vegetables and Other Ingredients
- Chop the Vegetables: Prepare the vegetables to complement the rich steak flavors.
| Vegetable | Preparation Details |
|---|---|
| Onion | Peel and slice into thick rings |
| Garlic | Peel and mince 4 cloves |
| Carrots | Peel and cut into 1-inch chunks |
| Celery | Trim ends and slice into pieces |
| Mushrooms (optional) | Clean and quarter |
- Mix Liquids: In a measuring cup, combine the following liquids:
| Liquid | Amount |
|---|---|
| Low-sodium Beef Broth | 1 cup |
| Red Wine | ½ cup |
| Worcestershire Sauce | 2 tablespoons |
| Tomato Paste | 1 tablespoon |
- Combine Ingredients: In the crock pot, layer the sliced onions, carrots, celery, and mushrooms (if using). Place the seasoned flat iron steak on top. Pour the liquid mixture evenly over the steak and vegetables.
- Add Garlic: Sprinkle the minced garlic over everything to enhance aroma and depth of flavor during slow cooking.
By preparing our flat iron steak in crock pot with care, we set the stage for a perfectly tender and flavorful dish that cooks effortlessly while we attend to other tasks.
Cooking Instructions
Follow these step-by-step cooking instructions to achieve tender and flavorful flat iron steak in crock pot that will delight every palate.
Browning the Steak (Optional)
Searing the flat iron steak before slow cooking boosts flavor and locks in juices. To brown the steak:
- Heat 1-2 tablespoons of oil in a heavy skillet over medium-high heat.
- Once oil shimmers, place the seasoned flat iron steak in the pan.
- Sear each side for 2-3 minutes until a rich golden-brown crust forms.
- Remove the steak and let it rest briefly before layering into the crock pot.
Note: Browning is optional but highly recommended for enhanced depth of flavor and attractive presentation.
Layering Ingredients in the Crock Pot
Proper layering ensures even cooking and flavor melding. Follow this sequence:
| Step | Ingredients | Instructions |
|---|---|---|
| 1 | Vegetables (onion, carrots, celery, mushrooms) | Spread evenly at the bottom of the crock pot. |
| 2 | Garlic cloves | Scatter over the vegetables. |
| 3 | Sear or raw flat iron steak | Place on top of the vegetables. |
| 4 | Liquid mixture (beef broth, red wine, Worcestershire sauce, tomato paste) | Pour evenly over the steak and vegetables. |
| 5 | Seasoning (additional herbs/spices if desired) | Sprinkle on top for enhanced aroma and taste. |
This layering traps steam and blends seasonings through the meat and vegetables during slow cooking.
Setting the Crock Pot and Cooking Time
To cook the steak perfectly:
- Cover the crock pot with its lid securely.
- Select the Low setting for tender, slow-cooked texture.
- Cook for 6 to 8 hours. For quicker results, use the High setting for 3 to 4 hours, but low heat is preferable for optimal tenderness.
- Avoid removing the lid frequently to preserve heat and moisture.
- Once done, verify the steak’s internal temperature reaches 145°F (medium-rare) to 160°F (medium), depending on preference.
Pro tip: Use a programmable crock pot with a timer to ensure consistent cooking without guesswork.
By following these precise cooking instructions, our flat iron steak in crock pot will turn out juicy, flavorful, and effortlessly tender every time.
