Grilled steak with horseradish cream and caramelized onions

Grilled Porterhouse Steak with Horseradish Cream and Caramelized Onions is a sumptuous and delicious dish that's perfect for any special occasion or just a great weekend barbecue. This recipe balances the robust flavors of the grilled beef with the tangy zest of horseradish and the sweetness of caramelized onions, creating a wonderfully harmonious meal that can impress any guest.

Instructions:

1. Prepare the Meat:
- Remove your porterhouse steak from the refrigerator and let it sit at room temperature for about 30 minutes. This helps the meat cook more evenly.
2. Season the Steak:
- Preheat your grill to medium-high heat.
- Pat the steak dry with paper towels.
- Season both sides of the steak generously with the black pepper and salt.
3. Grill the Steak:
- Place the porterhouse steak on the preheated grill.
- Grill for about 4-5 minutes on each side for medium-rare doneness. Adjust the time according to your preferred level of doneness.
- Once done, remove the steak from the grill and let it rest for at least 5-10 minutes. This allows the juices to redistribute within the steak.
4. Prepare the Horseradish Cream:
- In a small bowl, combine the light sour cream and the horseradish.
- Mix well until the ingredients are fully incorporated.
- Cover and refrigerate until ready to serve.
5. Caramelize the Onions:
- While the steak is grilling, heat a large skillet over medium heat.
- Add a bit of olive oil or butter to the skillet.
- Add the thinly sliced onions and a pinch of salt.
- Cook, stirring occasionally, until the onions are golden brown and caramelized. This should take about 20-25 minutes.
- If the onions begin to stick, you can add a splash of water to deglaze the pan.
6. Serve:
- Slice the rested porterhouse steak against the grain.
- Serve with a generous dollop of horseradish cream on the side.
- Top the steak slices with the caramelized onions or serve them on the side.

Grilled steak with horseradish cream and caramelized onions FAQ:

What is the grilling time for porterhouse steak?

For medium-rare doneness, grill the porterhouse steak for about 4-5 minutes on each side. Adjust the time based on your preferred level of doneness.

How do I know when the steak is done?

Use a meat thermometer to check the internal temperature. For medium-rare, it should be around 130-135°F (54-57°C). Let the steak rest for 5-10 minutes after grilling.

Can I make the horseradish cream in advance?

Yes, you can prepare the horseradish cream a day ahead. Store it in the refrigerator in an airtight container until ready to serve.

What type of onions should I use for caramelizing?

Yellow or sweet onions work best for caramelizing due to their natural sugars, which create a rich, sweet flavor when cooked.

What are some suitable substitutions for sour cream?

You can substitute light sour cream with plain Greek yogurt or a mixture of mayonnaise and yogurt if you prefer a different flavor or texture.

Tips:

- Ensure your grill is preheated to high heat before adding the steaks for the perfect sear.

- Season the steak generously with salt and pepper on both sides to enhance its natural flavor.

- Let the steak come to room temperature before grilling to ensure even cooking.

- Use an instant-read thermometer to check the steak's internal temperature for your desired doneness: 125°F for rare, 135°F for medium-rare, 145°F for medium, 150°F for medium-well, and 160°F for well-done.

- Allow the steak to rest for at least 5-10 minutes after grilling so the juices can redistribute, making the meat more tender and flavorful.

- For the horseradish cream, mix the horseradish with light sour cream and let it chill in the refrigerator for 30 minutes to meld the flavors.

- Slice the onions thinly and cook them slowly over medium-low heat until they are golden brown and caramelized, stirring occasionally to prevent burning.
