French Onion Garlic Butter Pork Roast: 5-Ingredient Crockpot Dinner

This five-ingredient crockpot pork roast is the weeknight dinner that practically makes itself. A tender pork sirloin roast simmers all day with sweet Vidalia onions, rich beef consommé, and a generous layer of cowboy garlic butter.

The result is fall-apart shredded pork in a silky, savory onion gravy that tastes like French onion soup meets garlic butter steakhouse. Just dump everything in the slow cooker in the morning, and by dinner you have a hearty, comforting meal that the whole family will love.

This recipe was born from a simple idea: take the flavors of French onion soup—caramelized onions, beef broth, and rich butter—and apply them to a budget-friendly pork roast. The slow cooker does all the work, turning a lean cut like sirloin into melt-in-your-mouth tender shreds.

The cowboy garlic butter adds a punch of herbaceous, garlicky richness that infuses the meat and onions as they cook.

It's the kind of dinner that fills the house with an irresistible aroma and makes everyone ask what's for supper. With minimal prep and maximum flavor, this is the perfect 'dump it and forget it' meal for busy days.

Ingredients

Why this recipe works

Slow cooking is the secret to transforming a lean, economical cut like pork sirloin into fork-tender perfection. The low, moist heat breaks down the connective tissue over hours, resulting in meat that shreds effortlessly. The onions melt into sweet, jammy ribbons that infuse the cooking liquid with deep, savory flavor.

The cowboy garlic butter acts as a built-in basting sauce. As it melts, it coats the roast with a blend of garlic and herbs, while the beef consommé provides a rich, umami-packed base. The combination creates a gravy that's both silky and intensely flavorful, without any extra thickening or fuss.

Notes and substitutions

Pork sirloin roast is a lean, affordable cut that works beautifully in the slow cooker. If you can't find it, a pork shoulder or butt roast will also work—just increase the cook time slightly.

Vidalia onions are sweet and mild, but any sweet onion variety will do; yellow onions are a fine substitute if that's what you have on hand.

Cowboy garlic butter is a compound butter with garlic, herbs, and often a hint of spice. You can find it in the dairy or meat section of many supermarkets, or make your own by mixing softened butter with minced garlic, parsley, thyme, and a pinch of cayenne. Store-bought garlic-herb butter works too.

• Vidalia onions: Sweet onions or yellow onions; use any sweet variety for the best caramelized flavor.
• Beef consommé: Beef broth or stock; choose low-sodium if preferred.
• Cowboy garlic butter: Store-bought garlic-herb butter or mix 4 tbsp softened butter with 1 tsp garlic powder and 1 tsp dried herbs.
