Step‑by‑Step Instructions for Slow-Cooked Sausage and Vegetable Casserole
Step 1: Heat the Oil
In a large skillet, heat 2 tablespoons of olive oil over medium heat until shimmering. This should take about 1-2 minutes. Once hot, it’s time to add the sausage, ensuring the oil coats the bottom of the pan for proper browning—this step is crucial for building rich flavors in your Slow-Cooked Sausage and Vegetable Casserole.
Step 2: Brown the Sausage
Add your Italian sausage to the skillet, breaking it apart with a wooden spoon. Brown the sausage for 5-7 minutes, stirring occasionally until it’s nicely golden and cooked through. The wonderful aroma will start to fill your kitchen! Once done, transfer the browned sausage into your slow cooker, leaving any flavorful drippings behind.
Step 3: Sauté Aromatics
In the same skillet, add diced onion and minced garlic, sautéing for about 3-4 minutes until the onion is translucent and the garlic is fragrant. This enhances the flavor base of the casserole. Once they’re softened, transfer this mixture to the slow cooker, mixing it with the browned sausage.
Step 4: Incorporate Vegetables
Now, it’s time to add the heartiness to your Slow-Cooked Sausage and Vegetable Casserole. In the slow cooker, combine chopped carrots, diced potatoes, bell peppers, and zucchini. Pour in the diced tomatoes and vegetable broth. Sprinkle in the dried oregano, basil, salt, and pepper, ensuring even distribution for robust flavor.
Step 5: Mix and Cook
Gently stir all the ingredients in the slow cooker until they are evenly combined. Set your slow cooker to low and cover it. Cook for 6-8 hours, or for a quicker option, set it to high for 3-4 hours. The mixture will bubble and blend beautifully, creating a comforting stew-like aroma.
Step 6: Add Final Touches
About 15 minutes before serving, lift the lid and stir in the frozen peas, letting them heat through. This adds a nice pop of sweetness and color to your casserole. Keep the cooker covered to maintain the warmth while everything melds together in delightful harmony for the ultimate comfort food experience.
Step 7: Garnish and Serve
When your Slow-Cooked Sausage and Vegetable Casserole is ready, give it a good stir. Garnish with freshly chopped parsley for a hint of brightness and visual appeal. Serve this hearty dish hot, and watch your family gather around, enjoying every delicious bite full of love and warmth!

How can I ensure my vegetables are fresh and perfectly ripe?

It will keep well in the freezer for up to three months. When you're ready to enjoy it again, just thaw it in the fridge overnight before reheating.
What if I have leftover sausage after making this dish?
You can certainly use leftover sausage in other recipes! Cooked sausage can be added to pasta dishes, breakfast scrambles, or even pizzas. Additionally, if you want to change it up next time, consider switching it out for lentils or plant-based meat for a vegetarian twist in your next Hearty Slow-Cooked Sausage and Vegetable Casserole.
Are there any dietary considerations I should keep in mind?
If you have dietary restrictions, check that your sausage and broth are labeled gluten-free if needed.
