To cook Costco Italian sausage, you can follow these steps:

  1. Preheat the oven to 400F.
  2. Line a baking sheet with foil or parchment paper.
  3. Put the sausages on a baking sheet in a single layer, so they are not touching.
  4. Bake for 25 minutes.

This is a simple and easy way to cook Costco Italian sausage. The sausages can be served on their own, or you can add some veggies alongside the sausage so they bake at the same time. You can also put in another baking sheet with potatoes to make best ever roasted potatoes.If you prefer to cook the sausages on the stovetop, you can follow these steps:

  1. Heat a large skillet over medium-high heat.
  2. Add a small amount of oil to the skillet.
  3. Add the sausages to the skillet and cook until browned on all sides.
  4. Reduce the heat to medium-low and continue cooking, turning the sausages occasionally, until they are cooked through. This should take about 15-20 minutes.

You can also grill the sausages, which is a great option for outdoor summer meals. To grill the sausages, preheat the grill to medium-high heat. Add the sausages to the grill and cook for about 5-7 minutes per side, or until they are cooked through.

Preparing Costco Italian Sausage for Cooking

Thawing Process

Start with patience—it’s the key when thawing. Gently transition your sausage from icy to ready-to-cook using the refrigerator, giving it time to evenly defrost.

This could take a bit, say, overnight. If pinched for time, the cold water technique can speed things up.

Seal it in a bag, submerge it in cold water, and change the water every 30 minutes. Safety comes first, always keeping temperatures in check to ward off any uninvited bacteria.

Pre-Cooking Preparation

Before the heat dance begins, grace the sausage skins with a few pricks. Why? It’s all about keeping them from bursting and letting those juices stay where the flavor party happens—inside.

Feel like a jazz artist when you season and marinate, riffing off garlic, fennel, or whatever herbs and spices strike you today.

Marinate, and let the flavors soak in, personalize it, make it sing with your culinary voice.

Cooking Methods

The grill is your stage, and it’s showtime. Stoke the flames to a medium heat, not too shy, not too bold.

Lay the sausages down, giving them space to bask in the glow. Turn them like you’re steering a symphony, and gauge doneness by that perfect char and a meat thermometer’s nod.


Picture a pan, your chosen vessel, shimmering with a film of oil. The heat’s just right; it whispers rather than shouts.

Lay the sausages in, listen to them sizzle, and watch for that satisfying crisp. Tend to them, rotate with care, because burnt isn’t a flavor we’re fond of here.

Oven Baking

Your oven is a trusty ally. Preheat it and prepare a tray, arrange the sausages with breathing room. They’ll bake evenly, turning golden as they bathe in the heat. Sometimes, a quick broil at the end gifts a kiss of crisp they yearn for.

Boiling and Simmering

In a pot, water or stock whispers, ready to welcome the sausages. They’ll simmer, not boil vigorously—it’s a gentle cook, infusing flavor all the way through. Add them to sauces or recipes and watch them become more than just a sausage—they’re a story.

Safety Considerations and Tips

Internal Temperature Guidelines

Here’s the unsung hero of our tale—the meat thermometer. It’s the surefire way to know when the sausage hits that safe internal temperature of 160°F for pork. This isn’t just about taste, it’s about the care we take when we cook.

Handling and Cross-Contamination

Take care as if you were a sculptor with their clay. Raw sausage is delicate; it demands respect. Work with it mindful of the other foods around, keep it separate, and clean as you go—cross-contamination is a tale for another day.

Storage of Leftovers

After the feast, cool them quick and whisk them into the fridge. If there’s a next round, a reheat to the right temperature is non-negotiable. Second verses of meals should be as safe as the first.

Creative Serving Suggestions

Traditional Italian Dishes

Marry sausage with pasta, tuck it into a sandwich hugged by peppers. It’s a nod to its roots, an homage to where it all began.

Innovative Pairings

But don’t stop there. Let imagination take the wheel—sausage meets seafood, sausage in fusion cuisine. It’s a daring twist to an old tale.

Breakfast, Lunch, and Dinner Ideas

Break the morning with sausage in your scramble. Crown your lunch salad with its hearty slices. End the day, casseroling into the night—a trilogy of meals sung with sausage.

Pairing with Side Dishes

Complementary Flavors

Side dishes are like the best backup singers—they make the star shine. Vegetables that resonate with the meat’s richness, starches that frame its flavor perfectly.

Wine and Beverage Pairings

Choose a wine that smiles back at the sausage’s richness or a non-alcoholic beverage that cleanses, making each bite a first encounter. The perfect sip is the one that respects the bite that came before and teases the next.
