Why Cook Pork Tenderloin in an Instant Pot?

• Speed: Traditional roasting takes 20-30 minutes, but the Instant Pot can cook pork tenderloin in under 30 minutes, including pressure build-up and release.
• Tenderness: The pressure-cooking process breaks down connective tissues, resulting in tender, juicy meat.
• Flavor Infusion: Cooking with broth, herbs, and aromatics infuses the meat with rich flavors.
• Versatility: Suitable for various cuisines—Asian, Mediterranean, BBQ, or classic roasted.
• Convenience: Hands-off cooking with minimal supervision.

Choosing the Right Pork Tenderloin

What Is Pork Tenderloin?

Pork tenderloin is a small, boneless cut of meat from the muscle that runs along the pig’s backbone. It’s known for its tenderness due to its location and minimal connective tissue.

How to Select a Quality Pork Tenderloin

• Freshness: Look for bright, pinkish-red meat with a clean smell.
• Size: Typically weighs 1 to 1.5 pounds. Choose a uniform size for even cooking.
• Packaging: If buying pre-packaged, check for proper labeling, no discoloration, and a clean appearance.
• Marbling: Slight marbling enhances flavor and juiciness but avoid excessively fatty cuts.

Alternatives and Variations

• Pork loin: Larger and less tender; requires different cooking times.
• Pork sirloin: Similar but slightly different cut.
• Boneless vs. Bone-in: Bone-in tenderloin adds flavor but takes slightly longer to cook and may require adjustments.

Preparing Pork Tenderloin for the Instant Pot

Basic Preparation

1. Trim excess fat: Remove any silver skin or excess fat for cleaner presentation.
2. Seasoning: Basic salt and pepper is fine, but you can add herbs, spices, or marinades.
3. Searing (Optional but recommended): Searing before pressure cooking enhances flavor and creates a crust.

Marinating (Optional)

• Marinate the meat for 1-4 hours in your favorite marinade—soy sauce, garlic, herbs, citrus, or BBQ sauce—to add flavor.

Searing the Pork Tenderloin

• Turn on the ‘Sauté’ function on your Instant Pot.
• Add a tablespoon of oil (olive, vegetable, or canola).
• When hot, sear the tenderloin on all sides until browned (~2-3 minutes per side).
• Remove and set aside.

Searing is optional but highly recommended for added flavor and texture.

Cooking Tips and Best Practices

• Use enough liquid: At least 1 cup of broth or liquid is necessary for pressure cooking.

• Use a meat thermometer: Always verify doneness with a reliable instant-read thermometer.
• Rest the meat: Let the pork rest for 5 minutes before slicing to retain juices.
• Slice against the grain: For maximum tenderness, cut slices perpendicular to the muscle fibers.

• Roasted vegetables: Carrots, Brussels sprouts, sweet potatoes, or green beans.
• Salads: Arugula, spinach, or mixed greens with vinaigrette.
• Grains: Rice, quinoa, or couscous.
• Mashed potatoes: Creamy and comforting.
• Applesauce or fruit compote: Adds sweetness and complements the pork.

Storage and Reheating

• Refrigerate leftovers: Store in an airtight container for up to 3-4 days.
• Freeze: Slice and freeze in airtight containers for up to 3 months.
• Reheat: Use the microwave or oven for best results. For moist reheating, cover with foil and reheat at 350°F (175°C) until warmed through.
