Grilled Pork Tenderloin: A California Grill Classic at Home

My first trip to Disneyland as a wide-eyed kid remains a treasured memory, but it was the California Grill atop the Contemporary Resort that truly elevated the experience. Even amidst the fireworks and the thrill of Space Mountain, the Grilled Pork Tenderloin stood out. The symphony of flavors—the tender, perfectly grilled pork, the creamy polenta, and the rich balsamic mushrooms—created a culinary memory that has stayed with me for years, one I’ve attempted to recreate many times over. It seemed impossible to capture, like trying to bottle pixie dust. But with this recipe, you too can conjure some of that Disney magic in your own kitchen.

• For the Balsamic Mushrooms:

Equipment Needed

• Cast-iron skillet
• Sauté pan
• Grill
• Baking pan
• Crock-pot (optional, for serving polenta)

Instructions

1. Prepare the Pork Tenderloin: Coat the pork tenderloins with olive oil and season generously with salt and pepper.
2. Sear the Pork: Sear the seasoned pork tenderloins in a hot cast-iron skillet, browning on all sides. This step is crucial for developing a rich crust. Set the seared pork aside for grilling later, reserving the pan juices in the skillet – these are liquid gold!
3. Make the Mustard Butter: In a bowl, combine the softened butter, Dijon mustard, whole grain mustard, lemon juice, Worcestershire sauce, salt, and pepper. Mix until well blended. This mixture will be used to baste the pork during grilling, adding moisture and a complex layer of flavor. This recipe yields enough butter for 3 to 4 pounds of pork tenderloin.
4. Sauté the Onion and Garlic for the Polenta: In a separate saucepan, sauté the diced white onion in a small amount of olive oil until transparent. Stir in the diced garlic and sauté briefly until fragrant, being careful not to burn it.
5. Cook the Polenta: Add the water, milk, and heavy cream to the saucepan with the sautéed onion and garlic. Bring the mixture to a boil. Once boiling, slowly whisk in the polenta, stirring constantly to prevent lumps from forming.
6. Thicken the Polenta: Continue to stir the polenta as it thickens and bubbles. Cook for 2 to 3 minutes, ensuring it doesn’t stick to the bottom of the pan. Remove from the heat and let it thicken for another 5 minutes. The polenta should be creamy and relatively thick, but still pourable.
7. Bake the Polenta: Pour the polenta mixture into a baking pan and bake in a preheated oven at 275 degrees Fahrenheit for 25 minutes. This baking step further develops the flavor and ensures a consistent texture.
8. Finish the Polenta: Remove the polenta from the oven and fold in the grated asiago cheese, crumbled goat cheese, and finely chopped fresh herbs. Season with salt and pepper to taste. Pour the finished polenta into a crock-pot to keep it warm for serving, if desired.
9. Prepare the Balsamic Mushroom Sauce: Place the minced shallots in the cast-iron skillet used to sear the pork tenderloin (containing the reserved pan juices). Sauté the shallots, stirring frequently, until softened.
10. Deglaze the Pan: Deglaze the pan with the dry red wine and balsamic vinegar, scraping up any browned bits from the bottom of the skillet. Reduce the liquid by half to concentrate the flavors.
11. Simmer the Sauce: Add the chicken or beef stock to the reduced wine and vinegar mixture. Continue cooking until the liquid has reached a light glaze consistency, stirring occasionally. This reduction process intensifies the balsamic flavor and creates a luscious sauce.
12. Smoke the Mushrooms: Wash, slice, and season the assorted mushrooms with a little olive oil, salt, and pepper. Pleau (the original California Grill chef) uses criminis, but portobellos, oysters, and shiitakes also work well. Spread the mushrooms out on a grill rack and place over low heat. Cover for a few minutes to lightly smoke the mushrooms. This adds a wonderful depth of flavor to the dish.
13. Combine the Mushrooms and Sauce: Combine the smoked mushrooms with the reduced balsamic glaze. Set aside to keep warm.
14. Grill the Pork Tenderloins: Grill the pork tenderloins over a low to medium fire, turning frequently to lightly brown on all sides (approximately 20 minutes). Basting occasionally with the mustard butter during grilling keeps the pork moist and adds a delicious glaze. Continue to grill until the tenderloins reach the desired level of doneness. The internal temperature should reach 145°F for medium. Use a meat thermometer to ensure accuracy. Let the pork rest for 5-10 minutes before slicing.
15. Serve: To serve, place a generous scoop (about a cup) of polenta on each plate. Slice the pork tenderloins into thick coins and arrange five coins in the center of the polenta. Ladle the balsamic mushroom sauce generously over the pork coins and top with a few fresh leaves of sage or parsley for garnish.

Expert Tips & Tricks

• Don’t overcook the pork tenderloin! It’s best served medium, with a slight pink hue in the center. Overcooked pork will be dry and tough. Use a meat thermometer to ensure precise doneness.
• Make the polenta ahead of time. You can prepare the polenta up to a day in advance. Reheat it gently on the stovetop with a little extra milk or cream to restore its creamy consistency.
• Smoking the mushrooms is optional, but highly recommended. If you don’t have a grill or smoker, you can sauté the mushrooms in a pan with a little olive oil until tender.
• Adjust the balsamic reduction to your liking. If you prefer a sweeter sauce, add a tablespoon of honey or maple syrup during the reduction process.
• Use high-quality balsamic vinegar. The quality of the balsamic vinegar will significantly impact the flavor of the sauce. Look for a balsamic vinegar that is thick and syrupy with a rich, complex flavor.

Serving & Storage Suggestions

Serve the Grilled Pork Tenderloin immediately after grilling for the best flavor and texture. Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat the pork gently in a skillet or oven until warmed through. The polenta can also be reheated on the stovetop with a little milk or cream to restore its creamy texture. The balsamic mushroom sauce can be reheated in a saucepan over low heat. The pork is best served fresh, but the polenta and sauce components will store well separately. Do not leave the dish at room temperature for more than 2 hours.

Variations & Substitutions

• Gluten-Free: Ensure all ingredients are gluten-free, especially the Worcestershire sauce and stock.
• Vegetarian: Substitute the pork tenderloin with grilled halloumi cheese or thick slices of portobello mushrooms for a vegetarian option.
• Dairy-Free: Use plant-based milk and cream alternatives for the polenta. Nutritional yeast can add a cheesy flavor. Omit the cheeses or substitute with a dairy-free alternative.
• Seasonal Herbs: Feel free to adjust the herbs used in the polenta based on what’s fresh and available. Try adding some fresh basil or oregano in the summer or using heartier herbs like rosemary and thyme in the winter.
• Polenta Texture: Adjust the amount of liquid when making the polenta based on the desired texture. For a looser polenta, add more liquid. For a thicker polenta, use less.

FAQs (Frequently Asked Questions)

Q: Can I make the mustard butter ahead of time?
A: Absolutely! In fact, it’s recommended. Making the mustard butter a day or two in advance allows the flavors to meld together even more. Just store it in the refrigerator and bring it to room temperature before grilling.

Q: What kind of mushrooms should I use?
A: The recipe calls for assorted mushrooms, so feel free to get creative. Crimini mushrooms are the classic choice, but portobellos, shiitakes, oyster mushrooms, or even a mix of wild mushrooms would work well.

Q: How do I know when the pork tenderloin is done?
A: The best way to ensure the pork is cooked to perfection is to use a meat thermometer. Insert it into the thickest part of the tenderloin. It should read 145°F for medium. Remember that the internal temperature will continue to rise slightly after you remove it from the grill.

Q: Can I use dried herbs instead of fresh herbs for the polenta?
A: Yes, you can! If using dried herbs, reduce the amount by half, as dried herbs have a more concentrated flavor.

Q: What can I serve with this dish?
A: The Grilled Pork Tenderloin is a complete meal on its own, but it would also pair well with a simple green salad or some roasted asparagus. A dry red wine, such as a Cabernet Sauvignon or Merlot, would complement the flavors nicely.
