Cooking Techniques
Making this amazing stuffed shells recipe is easier than you might think! The key is tempering the eggs – this means slowly warming them up by adding hot liquid a little at a time. This stops them from scrambling when added to the sauce. Just remember to keep stirring as you add the hot cream mixture to the eggs, and you’ll get a perfectly smooth and creamy alfredo sauce every time.
Smart Substitutions
Short on time? Use store-bought alfredo sauce instead of making it from scratch – you’ll need about 3 cups. For a lighter version, swap the heavy cream for half-and-half (the sauce will be a bit thinner but still tasty). No fresh broccoli? Frozen works great too – just thaw and drain it well before mixing with the chicken. You can also use turkey instead of chicken, or add some sautéed mushrooms for extra flavor!
Storage Tips
These stuffed shells are perfect for making ahead! You can keep them in an airtight container in the fridge for up to 3 days. To freeze, assemble everything but don’t bake – cover tightly with foil and freeze for up to 2 months. When ready to eat, bake straight from frozen at 350°F for about 45-50 minutes until hot and bubbly. The sauce might look a little separated when reheating – just give it a gentle stir and it’ll come back together.
Serving Suggestions
Round out this cozy meal with a simple green salad and some warm garlic bread to soak up that amazing alfredo sauce. Want to add some color to your plate? Roasted cherry tomatoes make a beautiful and tasty garnish. For a fun family-style dinner, put extra warmed alfredo sauce in a little bowl on the table – everyone loves extra sauce for dipping!
