This Cheesy Chicken and Vegetable Keto Casserole is the ultimate comfort food for anyone looking to satisfy those hearty cravings without the extra carbs. It features a rich, velvety base made from a blend of cream cheese, cottage cheese, and sour cream that perfectly coats every piece of tender chicken and garden-fresh vegetable. You will love the contrast between the bubbly, golden-brown cheddar crust on top and the creamy, savory center that feels like a warm hug in a bowl. It is a fantastic way to pack in your greens, as the spinach, zucchini, and Mexican squash soak up all those delicious cheesy flavors, making it a hit even for the pickiest eaters at the table.
One of the best things about this dish is how easily you can customize it based on what you have in your refrigerator. If you cannot find Mexican squash, simply double up on the zucchini or swap it out for some steamed broccoli florets or cauliflower rice for a different texture. For those who prefer a little extra kick, try using pepper jack cheese instead of cheddar, or toss in some red pepper flakes to brighten up the creamy sauce. If you are using fresh spinach instead of frozen, just make sure to sauté it briefly and squeeze out any excess moisture before folding it into the cheese mixture to ensure your casserole stays perfectly thick and indulgent rather than watery.
This casserole is a meal prep dream, as the flavors often deepen and become even more delicious the next day. You can store any leftovers in an airtight container in the refrigerator for up to four days, or freeze individual portions for a quick and easy dinner later in the month. When you are ready to enjoy it again, reheating is a breeze. For the best results, place a portion in the oven at 350 degrees Fahrenheit until it is heated through and the cheese is sizzling again, though a quick zap in the microwave works perfectly well for a busy lunch. Just be sure to give it a little stir if you find the cheese sauce needs a bit of re-incorporation, and you will have a meal that tastes just as fresh as the moment it first came out of the oven.
