Step-by-Step Instructions
Prepping the Broccoli
Start with fresh broccoli florets. Wash them well under cool water. If the florets are large, cut them into smaller pieces. This helps them cook evenly. You want bite-sized pieces for easy eating. Once you chop the broccoli, set it aside.
Mixing the Ingredients
Grab a large mixing bowl. Add the cooked quinoa first; it gives a nice base. Next, add minced garlic and grated Parmesan cheese. Pour in heavy cream and vegetable broth. Sprinkle in onion powder and garlic powder for extra flavor. Don’t forget to add salt and pepper to taste. Mix everything well until smooth and creamy. Now, fold in the broccoli florets gently. Make sure they are well coated in the mixture.
Cooking in the Slow Cooker
Take your slow cooker and lightly grease it with olive oil. This step keeps the casserole from sticking. Pour the broccoli and quinoa mixture into the slow cooker. Cover it and set it to cook on low for 3 to 4 hours. You want the broccoli to be tender and the mixture bubbly. About 30 minutes before serving, add shredded mozzarella cheese on top. Cover it again to let the cheese melt. For a crunchy finish, toast breadcrumbs in a pan with olive oil until golden, then sprinkle on top. Finally, garnish with chopped parsley for a nice touch before serving.
Tips & Tricks
How to Perfectly Cook Broccoli
To cook broccoli just right, start with fresh florets. Look for bright green color and firm stems. Cut large florets into smaller pieces. This helps them cook evenly. When adding them to the slow cooker, make sure they are coated well in the creamy mixture. This will help them soak up all the flavors. Cook them until they are tender but still bright green. Overcooking can make them mushy and dull.
Adjusting Creaminess and Cheese Levels
If you want a creamier casserole, add more heavy cream. You can also mix in extra cheese, like more Parmesan or mozzarella. Just remember, too much can make it greasy. If you prefer a lighter dish, reduce the cream and cheese. Use low-fat options for a healthier take. This way, you can still enjoy the rich flavors without the guilt.
Equipment Suggestions for Slow Cooking
Using the right slow cooker makes a big difference. Choose one with a good seal to keep moisture in. A 4-quart slow cooker works well for this recipe. I like to use a non-stick slow cooker to make cleanup easier. A spatula is helpful for mixing and serving. Make sure to have measuring cups on hand for accuracy. This will help you get every ingredient just right.
Variations
Adding Proteins
You can add proteins to the casserole to make it more filling. Chicken, turkey, or shrimp work well. Simply cook the meat first and mix it with the other ingredients. If you use chicken, I suggest shredded rotisserie chicken for ease. For shrimp, cook them until just pink, then fold them in gently. This will add flavor and a nice texture to your dish.
Vegetarian Options
If you want a vegetarian twist, replace the quinoa with chickpeas or lentils. Both options are rich in protein and add heartiness. You can also toss in some diced bell peppers or mushrooms for extra flavor. These veggies pair well with garlic and cheese. They add a nice crunch and color to the casserole.
Gluten-Free Modifications
To make this casserole gluten-free, skip the breadcrumbs or use gluten-free ones. You can also add crushed gluten-free crackers for a similar crunch. Be sure to check that your cheese and broth are gluten-free as well. This way, you keep the flavors while making it safe for everyone to enjoy.
Storage Info
Storing Leftovers
After enjoying your Slow Cooker Garlic Parmesan Broccoli Casserole, you may have some leftovers. To store them, let the casserole cool to room temperature. Then, transfer it to an airtight container. Make sure to cover it tightly to keep it fresh. You can store leftovers in the fridge for up to 3 days.
Reheating Instructions
When you are ready to enjoy your leftovers, reheating is easy. You can use the microwave or oven. If using the microwave, place a portion in a microwave-safe dish. Heat in 30-second intervals until warm. If you prefer the oven, preheat it to 350°F (175°C). Place the casserole in an oven-safe dish and cover with foil. Heat for about 15 minutes or until hot throughout.
Freezing Tips
If you want to save some for later, freezing is a great option. First, let the casserole cool completely. Then, portion it into freezer-safe containers or bags. Remove as much air as possible before sealing. Label with the date and type. You can freeze it for up to 3 months. To reheat, thaw it overnight in the fridge and then follow the reheating instructions above.
FAQs
Can I use frozen broccoli instead of fresh?
Yes, you can use frozen broccoli. Just remember to thaw and drain it first. Frozen broccoli cooks faster than fresh. So, check your casserole sooner. This helps keep the broccoli from getting mushy.
What can I substitute for heavy cream?
You can replace heavy cream with milk mixed with a bit of butter. Use ¾ cup of milk and ¼ cup of melted butter to mimic the thickness of cream. Another option is to use coconut cream for a dairy-free twist. Both will keep your casserole creamy.
How do I know when the casserole is done?
Check the broccoli for tenderness. It should be bright green and soft when you poke it with a fork. The mixture should also be bubbly around the edges. If you see this, your casserole is ready to enjoy!
